The four friends head back to their motel room. They were doing their usual thing. Sam was on his computer, Cas was looking through books, Dean was drinking, and Emily was plucking her eyebrows with tweezers.
"Ouch!" Emily reacted to the little pain in her forehead. "Son of a bitch!"
"Is it customary to constantly groom yourself, Emily?" Cas questions her.
"Cas, this is how girls are," she explains to him. "If you had taken a female vessel, you'd be too busy grooming yourself. Unlike you three, I have to get rid of hair in places where hair should not be on a woman's body."
"Like the time you fell asleep with waxing lotion on your lip and got second degree burns?" Dean smirks.
She shrugs her shoulders. "I just told people I had herpes." Emily awkwardly said. "The only person who will actually believe me is my best friend here." She glances over at Cas.
"I'm your best friend?" He tilts his head in confusion.
"Of course, Cas. Don't you read my blog?"
Before Cas could answer, Sam interrupts, "It's okay if you don't, Cas. Dean and I don't read them either."
"So anything at all, Sam?" Dean asked him.
"There is no stories or legends about any people uncontrollably singing or dancing. Anything could be causing this. A witch or…a person with magic."
"Well whatever it is obviously knows us." Emily brought up.
"What do you mean, Em?" Sam asked her.
"Think about it, guys. This witch or warlock knows us. Why else would it erase the memories in everybody else's minds except ours if they didn't know us?"
All three men exchanged looks. Castiel agrees, "Emily does a point. We are the only ones who remember singing."
"So what now?" Dean asks. "We're gonna keep singing in the rain while everybody forgets what happened."
"If so, why are they doing this?" Sam says. "There has to be a reason for all of this."
"Maybe there's a moral of this here." Emily suggested. "You sing and dance…for no apparent reason at all."
"Okay, well just wait until we start singing again." Dean rolls his eyes. "Great."
"Whatever this is…isn't really harmless to anybody," Cas added. "There has been no murders or deaths reported."
"So this is just a prank or something," Sam said. "No killing or dying."
"So is this a case or what?" Emily asked.
"This is by far the weirdest thing ever. I-I don't even know where to start."
"Maybe we should ask the people if they have noticed anything suspicious," Dean suggested. "Come on."
"Awesome!" Emily shrieked. "We're like the dream team here!"
"No dream team, Emmy." Dean tells her.
"Come on, Dean! The four of us are practically the Golden Girls. I'm Sophia, Cas is Rose, you're Blanche, and Sam is Dorothy."
"Why the hell am I Blanche?" Dean asked.
"Don't sass me," Emily warns him.
"Okay, well let's go see if anything is suspicious again." All of them head out the door and walked towards the Impala.
"How old is this car anyways?" Emily comments. "I'm surprised it's still going."
"Em, first of all, it's not an it." Dean tells her. "She is Baby. She has been a part of this family before me and Sam existed."
Dean: Why this car is systematic
It's hydromatic
It's ultramatic
Why it's a grease lightning (Grease lightning)
Dean throws off his jacket and starts singing.
We'll get some overhead lifters and four barrel quads
Oh yeah
(Sam: Keep talking whoa keep talking)
Fuel injection cutoffs and chrome plated rods oh yeah
(Sam: I'll get her ready, I'll kill to get her ready)
With the four speed on the floor they'll be waiting at the door
You know that ain't no shit we'll be getting lots of tit
In Grease Lightning
Go, go, go, go, go, go, go, go, go, go
The four of them hopped onto the car and replicated the number.
Go grease lightning you're burning up the quarter mile
(Grease lightning go grease lightning)
Go grease lightning you're coasting through the heat lap trial
(Grease lightning go grease lightning)
You are supreme the chicks'll scream for grease lightning
Go, go, go, go, go, go, go, go, go, go
We'll get some purple hued tailpipes and some thirty inch fins
Oh yeah
We'll pound 'em in the dashboard and duel muffler twins
Oh yeah
With new pistons, plugs and shocks I could get off my rocks
You know that I ain't bragging she's a real pussy wagon
Grease lightning
Go grease lightning you're burning up the quarter mile
(Grease lightning go grease lightning)
Go grease lighting you're coasting through the heat lap trial
(Grease lightning go grease lightning)
You are supreme the chicks'll scream for grease lightning
Go grease lightning you're burning up the quarter mile
(Grease lightning go grease lightning)
Go grease lighting you're coasting through the heat lap trial
(Grease lightning go grease lightning)
You are supreme the chicks'll scream for grease lightning
Lightning, lightning, lightning
Lightning, lightning, lightning
Lightning
Once they stopped, they immediately get off the car. "Okay," Sam gasped. "I didn't really like Grease, but I actually enjoyed that part."
"What the hell was that?" Dean demanded.
"It's like every time we say something, a song starts," Emily says.
