How is duct tape like the Force?
It has a light side...
...it has a dark side...
...and it binds the universe together :o)
I first heard that joke in the SCA (Society for Creative Anachronism, the medieval recreation group). We use a lot of duct tape in the SCA, which ironic considering the group's purpose, but duct tape is the perfect thing for covering a rattan sword, or for repairing the edging on a shield or for holding bits of broken armor together....
Not if you consider the "Anachronism" part...
OTOH, food poisoning was "period."
