How funny is this joke on a scale from 1 to 10?

Tell me how much you liked the joke, also.

So this guy Is Driving along, he's been driving for miles and he has to pee, so he pulls over at this bar where they obviously have a bathroom, so he runs through the parking lot and into the bar and asks the bar tender where the bathroom is, he replies, "Down the hall to the left." so the guy runs down the hall and runs into the bathroom and he sees three guys doing the dirty monkey dance all at the same time at a urinal, he’s absolutely disgusted and still had to pee and ran to the last stall to relieve himself after an awkward moment he ran out and asked the bar tender if he knew of the atrocity's happening in his bathroom and so he told the bartender and he paused and thought and asked, "was the guy in the middle wearing a pink shirt?"....and the guy thought about it and said,"well yah, but what does that have to do with it?" and the bartender replied, "damn hes good at cards too, that lucky bastard!"
