Well, it all started when Rigby and Mordecai were playing video games. Mordecai keep winning and wining, and then he joked at Rigby, saying thing like "You're the worst video game player, like ever", and Rigby get tired and screamed "I'm done here, dude".
Rigby opened the main door and left, he walked thru the park and ran to the woods. He sat on the ground and just thought how he wanted to win sometimes. Suddenly he heard a strange noise like footsteps, so he turned around, but he didn't saw anything, he thought he was going crazy or something, because the noise was getting closer and louder, but the thing was… that he couldn't see no one. He started running, to nowhere.
When he stopped running he was in the city, so he could only think of getting into Eileen's house.
He knocked on the door, and she quickly opened saying "ah..Rigby, what are you doing here at 1 a.m.?", "Well, you're probably not going to believe this but, I was in the park, and then in the woods, and then some creepy guy started chasing me and I just started running, and then end up here…" he said still trying to get his breath.
"Well, I guess you're ok now, right ?" she said in her sweet voice.
"Yeah, yeah, I'm all right."
"You want me to drive you home ? she asked.
"Yesss, that would be cool."
While she was driving him home, she turned on the radio and started singing, and when the car stopped in front of the main access to the park, the were both singing and laughing at each other.
"So I guess that's it Rigby."
"Yeah, thank you Eileen, I had some fun, I guess."
"Yeah I guess." She said, getting into the car and going home, again.
Everything he could think of, were Eileen, so when he got to bed, he dreamt of her.
P.S: And probably, there was no creepy guy, and no strange noise, probably the only thing he wanted, was to get to her.
