not a heckle per-se but my mate stunned a comedian once
was at some comedy club in london a year or two back for a mates birthday, he'd imbibed a large amount of the party juice and was about as sure-footed as a one-legged mountain goat in an avalanche.

just before the start of one of the acts he gets up to go and grab a couple of pints, the comedian starts up and is getting into the flow of things when my mate returns pint in each hand and starts shuffling along our row (and this is important to note: the rows were crooked and halfway down they made a 30 degree angle to go down the side of the stage and at this point there is a small step) my friend not realising there was a step trips over it, he shouts "oh fuck" and then down he goes like a sack of the proverbial, outstretching his arms in an attempt to break his fall, however he's still clutching his two pints so as he falls he slams the two pints perfectly flat on the ground, the glasses remain intact but the resultant force causes all the beer inside to be ejected straight up into the air causing two 6 foot beer fountains that rained down on everyone in a 2 row vicinity.

the comedian having heard my mates shout must have turned just in time to see the beer shoot up in the air from behind some seats and was so puzzled he actually stopped talking and just stared for abut 10 seconds with a confused look on his face and forgot totally what he was saying.
