A guy walks into an ice cream parlor and asks, "May I have a scoop of chocolate please?"
The attendant replies, "I'm sorry sir, but we're out of chocolate."
The customer thinks for a second and then asks, "Well then may I have a pint of chocolate?"
The attendant replies, "I said that we are out of chocolate sir."
The customer scratches his chin and then asks, "Well how about a gallon of chocolate?"
The attendant sighs and calmly replies, "Sir, can you spell the 'straw' in strawberry?"
"Sure, S-T-R-A-W"
"Can you spell the 'van' in vanilla?"
"Of course, V-A-N"
"Now, can you spell the 'fuck' in chocolate?"
The customer looks puzzled and replies, "There is no fuck in chocolate."
"THAT'S WHAT I'VE BEEN TRYING TO TELL YOU!!!"
