Headphones
Gonad used to enjoy playing with regular walkman headphones. There are always
a lot of them around the house that don't work, so I would drag them about,
watching Gonad chase them. One day when Soraya and Joel were over, my mom
came into the living room holding a pair of headphones. She said "Are these
Gonad's?"
"No," replied Joel, "they're headphones."
To this day we still refer to headphones as gonads.
