The setting is a simple sidewalk. There should be a sturdy wall of some sort in the background, and a dirty looking trash can sitting close by.
Boy 1: (Walks in listening to his iPod, singing along - out loud - while chewing gum. The goofier the song, the better. He gets to where the trashcan is located, and stops. He takes the gum out of his mouth and sticks it to the wall somewhere close to the trash can. Then he exits the scene, continuing to sing.)
Boy 2: (Walks in from the same directions as Boy 1 and heads toward the trashcan. When he gets to where the gum is located, he notices that his shoe is untied. He bends over to tie his shoe, and when he goes to stand up, he places his hand on the wall, right where the chewing gum is.) "Oh, man! Bubble gum! Yuck!" (He then stoops over and begins to wipe his hand across the ground to rub it off on the sidewalk. When he frees himself from the gum, he leaves the stage.)
Boy 3: (Walks in from the same direction playing with a cell phone or video game, not really watching where he is going. He steps in the gum on the ground and comes to a stop. He looks down and notices the gum.) "I think people who spit their gum on the sidewalk should all be abducted by aliens - for the purpose of strange experiments!" (He then takes the gum off of his shoe and puts it in the trashcan. Then he leaves, playing with game.)
Boy 4: (Walks in from the same direction with a cup in his hand. As he approaches the trashcan, he takes one final, really long slurp from his drink, and then puts the empty cup in the trashcan. As he reaches into the trashcan, he gets the gum on his hand.) "Oh, dude, that is SO sick! This is somebody’s chewing gum… on my hand!" (He walks over to the wall and sticks the gum on it, then walks off shuddering in a grossed out manner.)
Boy 1: (Re-enters the scene from the opposite direction. He is now singing some other really silly song. He notices his chewing gum on the wall “right where he left it.” He reaches up to grab it and says…) "Hey! There’s my gum!" (He then pops it in his mouth and walks off the stage.)
Note: The secret to the success of this skit is that the bubble gum taken OUT of the trashcan should be a different piece from the one Boy 3 puts IN the can. Have Boy 1 chew a piece of gum and place it the trashcan, ready for Boy 4 to stick it on the wall. Make sure Boy 4 has very clean hands before coming on stage.
