The Electric Triangle is an instrument that Is quite peculiar. It is the musical "triangle" with electricity either flowing through it (which would make it almost impossible to play unless the musician was wearing rubber gloves!), or hooked up to an amplifier (which wouldn't be too hard, but it would take some creativity to do!).
Occasionally, people would die, so the battery-powered triangle was created. It allowed the same sounds to be made, but could be played without gloves without causing death, as the current was not as strong. It was also portable, which made it accessable to buskers, who didn't always have a source of power available.
Please do not confuse this for an object that does exist. It did not exist once in an episode of The Fairly Odd Parents so therefore it is not real and can be made into a joke at all whatsoever.
"My mom got me some chicken nuggets the other day. I asked for ketchup but she got me honey mustard. In revenge, I said "Yo! Motha! Come play my electric triangle!" Well, fun fact, my mom has a habit of sticking new things up her nose. You know, like when babies chew on everything to figure out what they are, yeah, that's my mom, just sticking things up one of her nasal cavities. Well, she had a runny nose that day, and she stuck it up her nose. Turns out 240 Volts of electric triangle being stuck up her nose wasn't the smartest of ideas, but she's all right. Needless to say, I now get ketchup with my nuggets whenever I want them."
