The budget for tasks has probably been cut to the bone, but surely there must be something else they can think up that wouldn't cost much to do? Seriously, we've seen the "eat something horrible, drink something horrible, get something horrible poured over your head" task at least once a week.
In the old days, they'd get them to stay up all night keeping a fire burning for 24 hours - can they not even afford a box of matches and some firelighters?
