Millets sell tents as does blacks pratice erecting tents and resiting everyday, you could also try crossing wires on car batteries, filling up gearboxes with vaseline, and watch casualty screaming in disgust at the poor standards of airway management.
Get a set of tank tracks and do some track bashing awesome fun!
Every couple of months give yourself an extra set of stripes,
Practice drinking, and casual sex,
Practice the bones song, knee bone connected the thingajig bone,
And go for bergan runs every friday for no absolute reason, prior to driving halfway across the country,
