i've got a buddy who works at UPS, and every year they hire people for a coupla weeks just for the christmas rush. so a bunch of years ago, he got me on that gig. i never knew you could play basketball, football, hockey, bowlin, heck, even horseshoes with cardboard boxes. there was also the game called "this is heavy, i bet you can't throw this up there."
funny thing is, out of the half-ton of packages i got from UPS, nothing was ever damaged. the only real problem i had was when the driver would leave my skateboards with the tweeker neighbor, and when i got the box it would be opened, with stuff missing...
