The Nintendo Power Glove, that is.
I have to admit I have never actually used this thing in conjunction with a video game. Sometimes I put it on and, channeling Darth Vader, pretend to “Force-choke” family members. Sometimes I put it on and make pretend beeping sounds while pressing the buttons. Sometimes I put it on, pump my fist into the air, and shout “Now you’re playing with power!”
Never would I put it on in the presence of other people. That would be weird.
