Impossible Sit up

A dirty trick you pull on a friend at a party, where you hold a towel over a friends face while he tries to do a sit up with you pulling down on it. While your friend tries to do this sit up you have another friend bend down over him and pull down his pants then you release the towel and your friends face goes into an asshole.

Kean: Aw man I was so drunk last night but I sobered up really fast when Darren and Matt got me to do an Impossible Sit Up.

Impossiblest

More impossible than impossible.

"Constructing a device that can access other dimensions is impossible, but even if it could be done, sending a human consciousness through it is... impossiblest!"

"Hey you remember Jason from 5th grade?"
"The nerdy kid, yeah, why?"
"He is dating Carol"
"But... this is impossiblest!!!"

Intermission Impossible

the sudden realisation that it would be impossible to make it to the intermission of some kind of theatrical production

within the first 10 minutes of Witches of Eastwick I figured 'Intermission Impossible', and had to figure out an escape plan
