the joke of 10 of march 2011

a cop pulls over a carload of nuns
cop: sister this is a 65 MPH highway -- why are you going so slow
sister: i saw a lot of signs that said 22, not 65
cop: oh sister, that's not the speed limit, thats the name of the highway your driving on!
sister: oh silly me! thanks for letting me know. ill be more careful.
At this point the cop looks in the backseat of the van and there he sees the other nuns shaking and trembling.
cop: excuse me, sister , whats wrong with your friends back there? they're shaking something terrible.
sister: oh, we just got off of highway 120.
