lol ok I'll admit it, I had to google wellington boots to see what they were :) But nah, you won't need those, some black pants will work just fine haha. Or pull-ups like Philber said, sounds like he got the royal treatment and I got the peasant treatment

In any case you'll be alright, they'll probably stick a big ball of cotton right in between yer cheeks afterward and it does a pretty good job of catching any "stuff."
Anyhow it's Wednesday morning for you now, must be close to showtime, hopefully everything's a go and there's no sick anesthesiologists to mess things up this time! Hopefully I'll wake up in the morning and see a post from you with good results and perhaps some drug-induced blabber :) Kiss that fissure goodbye for us!
