Scariest, and most embarrassing, water slide was at Waterworld in Cyprus.
Went on the Kamikaze slide (after a lot of egging on from mates) and as I went through the drop I was so scared I made the weirdest sound ever - it wasn't a scream it was like a big beasty bellow something like "guraaaaarghh" and everyone in the queue behind me heard it - probably the people watching as well - and not only that I had a v. painful wedgie!
Not good.
