Anti-aircraft Joe has his own thread on Arfcom, and a few good spoofs already.
For all the duct tape haters out there, ever see the Mythbusters Duct Tape Episode? They made a duct tape cannon of all things!!!
I posted about duct tape but it wasn't because of hate. Duct tape is awesome! Mythbusters also made a duct tape boat, they lifted a car with it, and if I remember right, they also made a foot bridge out of it!
