A drunk is sitting at a bar when Elrod stands behind him and raises his arm really high to get the bartender's attention.
He has very hairy armpits. The drunk sees this and yells at the bartender, "Get the ballerina a drink."
Elrod gets his drink and goes away.
Later he returns and raises his arm again. The drunk sees him and yells to the bartender, "Get the ballerina another drink."
He gets his drink and goes away again.
The bartender asks the drunk how he knows that he is a ballerina given that he is a stranger and has never been in the bar before.
The drunk replies, He's got to be a ballerina if he can lift his leg that high."
