Have two or three volunteers put a whole banana in their mouth, instructing them not to eat it, just hold it in their mouth.
Then put a pair of panty-hose over each volunteer’s head. Have them squish the banana through the tiny holes in the hose
into a trash or grocery bag.  This game is hilarious, because when you take the pantyhose off the students’ heads, the
banana still stuck in the hose is smeared across their face!
