Note: This is a gross skit. Only do this if you want to . . . and never "make" anyone be guy no. 5.
The scene opens with a glass of water on a table with a sign that reads, "Water out of order - this is the last glass."
Guys (or mix of guys/girls) enter one at a time (all in pajamas, if you want) as if there is a mirror and do different things with the water.
First guy combs hair dipping comb in and out of cup; second guy cleans ears (fake it but have flour on the Q-tip to cloud water); third guy rinses and spits toothpaste (frosting); fourth guy shaves (whipped cream). Guy No. 5 comes in to take aspirin and drinks the water!
