A man walks into an ice cream parlor. He asks the clerk for some chocolate ice cream. He says "Excuse me, I would like a gallon of chocolate ice cream".
The clerk replies, "I'm sorry sir, but we are all out of chocolate. We have Vanilla, or Strawberry"
The man thinks for a second, "Oh, alright. I would like a quart of chocolate ice cream"
The clerk says "Sir, I just told you we are out of chocolate"
"Oh, alright. I'll take a cone then"
"What flavor" The clerk asks
"Chocolate", says the man proudly.
The clerk sighs. "Alright, spell van, as in Vanilla"
The man blurts out "V-A-N"
"Good! Now spell straw, as in strawberry"
Again, the man blurts out "S-T-R-A-W"
The clerk says "Now spell fuck, as in chocolate"
The man asks confused "But there is no fuck in chocolate"
The clerk yells out "THATS WHAT I'VE BEEN TRYING TO TELL YOU!"
