Flashback
Freddy: This was just a few weeks after Marissa started diapering Freddy, she gave him a contract to sign; as he looked through it he saw a "baby clause", he asked his mom what it was.
Her reply, "A precaution, honey. It's just so if you fall into a coma the nurses can change you, it's not necessary, but it helps." Freddy then signed his doom.
Nevel: "Hey, Nevel, I have another document about Nevelocity for you to sign." Asks Nevels's mother.
Nevel too signed his doom.
Spencer: Spencer had just started dating Marcie, she too had him sign a contract, her reason "Spencer, I'm really into contracts and it just says you won't break up with me for at least 5 weeks."
"I'd never break up with you Marcie." And so he too, signed his doom; making it legal for what they're doing in the present.
A Month Later, Spencer:
"Spencer, I'm going to introduce you to my mom at dinner, okay?" asks Marcie.
"Sure." Answers Spencer, working on his newest sculpture, he wasn't really paying attention to what was happening; not to what he was agreeing to or to what Marcie was slipping in his drink.
When they got there, Spencer's bladder was near bursting, he ran up to the doors….. But was too late he had wet himself. Marcie saw and told him, "It's okay, I'll just make up some excuse to tell my mom. Just sneak into the back bathroom." Marcie hid her smile.
Present Day: Spencer was getting impatient so he started to look through the closets; he was just about to the one with the Spencer-sized baby stuff, when he heard Freddy and Nevel's crying. He opened the door; he was pushed back and the door closed. The women then pushed Spencer onto the changing table; Marcie then stripped him to his soaked boxers. Spencer struggled but the straps were tightened, and a pacifier from the closet put in his mouth. They then diapered him, put him in a yellow onesie, and sat him in the playpen with Freddy and Nevel.
