“My friend asked me if I wanted a frozen banana…” (joke)

Not everyone understands the concept of a frozen banana (a dessert on a stick). American stand-up comedian Mitch Hedberg (1968-2005) told this joke in his act by at least 1999:
 
“My friend asked me if I wanted a frozen banana, I said no, but I want a regular banana later, so…yeah.”
 
The line has been frequently cited as one of Hedberg’s best one-liners.
 
   
Wikipedia: Frozen banana
Frozen bananas are desserts made by placing a banana upon a stick, freezing it, and usually dipping it in melted chocolate. They may be covered with toppings such as chopped nuts, sprinkles, sugar and crushed cookies.
