It is actually quite hard to do the full 100 shots on the regimented minutes - normally when you drink you drink more than the 1 shot but you have a rest in between even if only for a few minutes.
Have completed it a few times but never without at least one tactical vomit!!
Next challenge double centurion - 200shots in 200 minutes!!!
The youtube vid linked to says you drink over 8 pints. Well a pint is 568ml. 8 of those is 4544ml. A shot is 25ml, divide that up and you get 181 shots. Just a bit over a hundred! Where do some of these people do their maths!

My advice on this one, is to not have the same pint twice. You'll be surprised at how much easier it is to drink a 'lot more' when the drinks are varied.
Can cause all sorts of fun later on, however...
