Red: I've got a better one.
[flashback to Red walking into the kitchen:]
Red: Kelso, it's 6:00 in the morning. Someone glue you to the fridge?
Kelso: No.
Red: Kelso, did you glue yourself to the fridge?
Kelso: Yes.
[After Kelso opens the refrigerator door for Red, Red grabs a carton of orange juice and slams the door shut, ripping Kelso's hand off the handle]
Kelso: [groans] Thanks, man.
[present:]
Angie: Why does he glue himself to stuff?
Kitty: Because he's a big dumb-dumb.
Eric: Next.
Donna: Okay, I got one.
[flashback to Donna walking out of the Formans' house:]
Kelso: Donna, check it out. I invented car skiing. [Donna gets into the car] Hit it, toots.
[present:]
Donna: You know, if there's anything he should have glued himself to, it was probably the top of that car.
