ok i got one its a bit long but its mine and my friends signiture joke: (dont question just use your imagination lol )
ok there were 3 guys in a hot air ballon, the ballon started to get heavy so they threw an axe out, the ballon rose but not long after it started to sink again so they threw an knife over the side, the ballon rose again, it started to sink again to they threw a hand grenade over the edge.
Later when they landed as they were walking along the street the found a women crying, they went up to her and said whats wrong? she said an axe fell from the sky and killed my husband, they quickly walk on and then come across a little girl crying, they asked her what was wrong? she said a knife fell from the sky and killed my dad, they quickly walk on and come across a man standing in front of a pile of rubble laughing his head off, they walk up to him and ask whats so funny? He turns and says . . . . . . . . i farted and my house blew up
