Scotch

A guy walks into a bar and asks for ten shots of the establishments finest single malt scotch. The bartender sets him up, and the guy takes the first shot in the row and pours it on the floor. He then takes the last one in the row and does the same. The bartender asks him, "Why did you do that?" And the guy replies, " Well the first shot always tastes like crap, and the last one always makes me sick!"
