Two drunks walk into a bar…

Two drunks walk into a bar. The first drunk looks at his buddy and says „I gotta go use the can.“ So he wonders off to the bathroom and is gone for 5 … 10… 20 minutes. Well his friend gets pissed off and goes in to get him. He findshim in there and asks „What the hell are you doing?“ The first drunk repies „Everytime I flush, something reaches up and grabs my balls.“ The second drunk looks at him and says“Well ya dumbass, you sittin on the mop bucket“
