to get the audience grossed out.
one person walks on stage and notices a fly. they swat it and say, “gotcha!” or another thing. then a person walks up and says” cool a fly! i’ll take it’s wings!” they pretend to pluck off the wings. others involved in the skit notice the fly and take it’s arms/legs/head/wings.it does not matter what order the parts get plucked. the last person says” cool! a raisin!” and picks it up and eats it.
