67. This is from Bill Hicks......Best Pun EVER

I love talking about Kennedy. I was just down in Dallas, Texas. You know you can go down there and, er, to Dealey Plaza where Kennedy was assassinated. And you can actually go to the sixth floor of the Schoolbook Depository. It's a museum called... 'The Assassination Museum'. I think they named that after the assassination. I can't be too sure of the chronology here but... Anyway they have the window set up to look exactly like it did on that day. And it's really accurate, you know, cos Oswald's not in it. "Yeah, yeh so wow that's cool." Painstaking accuracy, you know. It's true, it's called the 'Sniper's Nest'. It's glassed in, it's got he boxes sitting there. You can't actually get to the window as such but the reason they did that of course, they didn't want thousands of American tourists getting there each year going [Mimes looking out of window] "No fucking way! I can't even see the road. Shit they're lying to us. Fuck! Where are they? There's no fucking way. Not unless Oswald was hanging by his toes, upside down from the ledge. Either that or some pigeons grabbed onto him, flew him over the motorcade... Surely someone would have seen that. You know there was rumours of anti-Castro pigeons seen drinking in bars... Someone overhead them saying 'coup, coup' Coo.
