As a former bartender, bar jokes are a guilty pleasure of mine. Here are a few of my favorites.
*An amnesiac comes into a bar. He asks, "Do I come here often?"
*A default Sans Serif font walks into a bar. The bartender says, "Sorry, we don't serve your type here!"
*A giraffe walks into a bar. "High balls are on me!"
*A man walks into a bar with a slab of asphalt under his arm and says, "A beer please, and one for the road."
*A dyslexic guy walks into a bra.
And my most favorite of all is....
*A man walks into a bar and says, "Give me a beer before problems start!" Again, the man orders a beer again saying, "Give me a beer before problems start!" The bartender looks confused. This goes on for a while, and after the fifth beer the bartender is totally confused and asks the man, "When are you going to pay for these beers?" The man answers, "Ah, now the problems start!"
