Blame It On the Dog

So this guy gets a date with the hottest chick in town.  On the night he's
supposed to take her out, however, he gets a major case of the farts, and
worse, the date's going to be in the movie theatre!  He manages to make it
through the entire move without farting.  But the girl tells him, "My dad
insists that I take all the guys whom I'm dating to meet him."  The guy
has no choice if he wants to keep dating her, so he agrees.
At the fathers house, he sees this dog sitting by the couch, so he figures
he'll sit beside the couch and if he lets one off, the dog will take the
blame.  So he sits down and starts to talk to the dad, when all of a sudden,
pffft!  He lets one off.  The father says, "Ruff."  The guy's relieved that
the dog got the blame, so he relaxes a little.  Later in the night, the guy
lets another one go. Pffft!  Again, the dad says, "RUFF!"  Finally, at the
end of the evening, the guy is getting ready to leave, relieved that the
dog got the blame for his gas, when he lets yet another one off! PFFFFT!!!
And the father says, "RUFF!  Get away from that guy before he shits all
over you!"
