"No Chocolate Icecream" joke

A woman walks into an ice cream parlor and tells the guy behind the counter,
"I'd like a gallon of chocolate ice cream."
The counter man says, "I know that this may sound strange, but we don't have
any chocolate ice cream. We ran out and the delivery truck hasn't arrived yet."
She says, "In that case, I'll have half a gallon of chocolate ice cream."
"Ma'am, I just told you that I'm sorry, we don't have any chocolate ice cream."
"Okay, then I'll have a pint of chocolate ice cream."
"Look lady, I said we don't have ANY chocolate ice cream."
"That's okay, I'll have an ice cream cone with two scoops of chocolate."
The counter man is absolutely livid and says, "Lady, how do you spell the
'straw' in strawberry?"
She says, "S-T-R-A-W."
"Right, now how do you spell the' van' in vanilla?"
"V-A-N."
"Great, now how do you spell the' fuck' in chocolate?"
She says, "There is no' fuck' in chocolate."
"That's what I've been trying to tell you, THERE IS NO FUCKIN' CHOCOLATE!"
