Back in my college days, I went to a couple of parties as either Dirty Harry or a samurai.
At one, a guy was dressed as a knight and started poking at the "samurai varlet" with Excalibur, and muttering things you're expect to hear at a Renaissance Faire.
Bad idea.
Arthur's Excalibur was paper mache . . . the samurai's katana was real. Much hilarity ensued.
Connect the dots.
(Still funny in retrospect - nobody got hurt - but since I'm older and at least a
little wiser, I definitely will
not be repeating this.)
Once a kid came to my house holding a box of Frosted Flakes, through which a plastic toy sword had been driven . . . he was a cereal killer.
Another kid was wearing a sweatshirt and ball cap, each with the letter "P" boldly emblazoned on it. He had a bit of charcoal rubbed under his eye . . . he was a Black Eyed P.
Another time, I went to a Halloween party as Dilbert. Sad to say, I was able to duplicate his wardrobe from my closet, down to the black & red striped tie . . .
