Without a doubt has to be the jump. Where else can you see something like 7 out of 14 Z list celebrities getting injured whilst producing such rivetting sporting action as arg from TOWIE sliding down a hill on his arse and heather mills skiing in a straight line down a hill, all culminating in jump off where one person's long jump is compared to another's high jump to see who stays in. Parody TV at its best
Splash had a lot more action compared to the jump. At least in splash there were always a couple of celebrities who became half decent at it and did proper dives that were actually pretty impressive. In the jump it's still people 'racing' at a snail's pace and then sliding off a ski slope and falling off the end.
