Replying to It's my mate's 18th birthday tomorrow... how should i torture him?

he can be kind of a prick at times, so we're going to rip the pish out of him. here's the plan so far:
starting at 6pm. he goes w/ me to the whisky society final meeting which includes several bottles of cask strength whisky.

we go out to a brewery for a few pints afterwards so i can pick up my mobile from a friend.

then off for 9 holes of pub golf and the rose street crawl( the rose street crawl is suicide on a normal night)

if he's still standing, we'll finish him off w/ a dirty pint.

so what do i do after this? I'm thinking of involving this list of items:
Duck-tape
Knife
zip-ties
a bus stop
Aluminum nitrate
hair cliper
hair dye
magic marker
bread
Swans or ducks(preferably swans)


any suggestion?
