Heard this one at lunch today and I spit chewed up potato chips all over the parking lot.
B-Rad, feel free to delete this if it is a little over the top...

So a business man new to the San Francisco bay area was looking to get a drink after a hard day at the office. The first bar he goes into near the office was full of suits and just seemed to "stiff" to truly be able to relax and just have a drink or two.
The next place he goes into right down the street was way too loud and flashy for him he felt out of place..
So he goes a few blocks down the road and pops into a pretty cool looking place, seemed tastefully done, was clean and neat and everybody was real low key...There were few to no women around, but he doesn't seem to notice, he only wanted a drink or two and a cab ride home.
So he sits down at the bar, orders a drink and just sort of people watches for a bit, everybody seemed so friendly...
So after a couple of drinks, he thanks the bartender, throws down a nice tip and ask where he could find the restroom, the bartender says"just down that hall and down the stairs"...
He gets to the restroom without any drama and takes a whiz, as he turns around to wash his hands he is utterly shocked to see one guy bent over the counter top getting drilled from behind and the guy doing the drilling getting drilled also...
Partially in shock, he leaves the restroom and figures he should let someone know what the hell is going on in there.. He gets to the bar and quietly tells the bartender what's going on, the bartender looks at him and smiles and asks "was one of the guys wearing a red and white plaid shirt?" The guy says "Yeah! the one in the middle!", the bartender responds "Yeah, Ronnie is lucky at cards too"....
The man almost gets sick and leaves the bar...
