Apart from the guests being two of my favourite human beings of all time (which is why I was watching it), it was interesting to see the jokes about the Royal Family having Princess Di bumped off.
I'm not a massive fan of the film, but this scene always makes me laugh out loud. Will Ferrell is fantastic in it, and you can see Paul Rudd almost lose it in his 60% of the time line.
Got to love Only Fools, this is a couple of clips of a great episode where Del & Rodney play practical jokes on one another resulting in Rodney having a red sunburnt face after Del lets him lie in a tanning bed too long, so Rod decides to get his own back when Del tries to get out of hang-gliding (after Del falsely boasts to the others present he was a paratrooper!). The first vid is the set up and the second is the result of the joke.
This one is just brilliant for the opening joke which is funnier now with what happened over the last few years; and the lines, acting and timing are just so spot-on.
