Wind Factor

This guy takes his girlfriend out to dinner (at a buffet of course). They then go back to her apartment, sit down on the couch, and start smooching. Suddenly he leaves a big fart. Not wanting to embarrass him, his girlfriend says, "Fido, get out from under this sofa". They go back to their smooching, and a while later he leaves another loud fart. Once again she says louder, "Fido get out from under this sofa." As they get back into the throws of passion, yet again he blasts another fart, and his girlfriend says, " Fido get out from under this sofa - before he shits all over you."
