A daughter's prom is coming up, and she has no money for her dress.
She goes to her father: "Daddy, can I please get this dress for prom?"
He father says, "only if you give me a blow job".
The daughter is repulsed and declines.
A week later, and a week closer to prom, she asks, "Daddy, can I please, PLease get this dress?"
"only if you give me a blow job."
Again, she says no and walks away.

Eventually, the prom is tommorrow.
She is desperate, so she goes to her father, and asks one more time, Daddy, PLEASE, can I get this dress? "
Her father says, again, Only if you give me a blow job".
So she agrees, unzips his pants and goes to work.
Immediately she gags and shouts "EW YOUR DICK TASTES LIKE SHIT!!!"

Her father replies, "Your brother wanted to use the car last night".
