I've got a few.
A blonde suspects her husband of cheating so she buys a gun. She goes to her appartment and sees her husband in bed with another girl. Gun in hand, the blonde stares him down. She then puts the gun to her head. The husband pleads "don't do it". The blonde replies "your're next".
Three workmen are sitting on top of the empire state building, an englishman, an irishman and an american. The american says to the irishman, i bet that i can jump onto that cloud and jump back. The irishman says "no you can't". So the american does it. He says "wanna see me do it again". So he does it again. The irishman gives it a go and falls through the cloud to his death. The englishman says to the american "you can be a real ***** sometimes super-man".
Two hunters are out in the woods when one of them collapses. He doesn't seem to be breathing and his eyes are glazed. The other guy takes out his phone and calls the emergency services. He gasps: "My friend is dead! What can I do?" The operator says: "Calm down, I can help. First, let's make sure he's dead." There is a silence, then a gunshot is heard. Back on the phone, the guy says: "OK, now what?".
