I once had a tapeworm. Would've had to wait 6 months to get it removed. Instead what i did was buy 2 mars bars and 3 twixes. Day one i put a mars bar up my bum and let him eat it. day 2 i put a twix up there for him. Day 3 - mars bars. Day 4 - twix. When day 5 came i put the last twix up there and when he poked is head out to ask "oi! Where's me mars bar?!" I grabbed him!
