pissing in the movie theater

i was having a piss in the movie theater...( well , not in the theater itself , but in the washroom )...and i though my friend was in the pisser next to mine...instinctively , i always have something stupid to say...and since his urinal was one of those ones for little kids...i came up with this..."get on your knees , you bastard "...luckily...i took a look first...and there to my left was some huge mother fucker foaming at the mouth...(exaggeration)... LESSON...look before you call some giant a bastard...or anything derogatory , for that matter .
