Not a gadget in terms of being powered by electricity, this Babykeeper harness keeps your baby safe while you use the facilities at ball games, strip clubs, and crack houses. Hold on Tommy, daddy's gotta drop a deuce! Who's a good little boy, who's a good *uuuuuughn* little boy!
Presumably the baby faces inside the stall and not out, which would make for quite a strange greeting as fellow dump-ateers enter the facilities. Of course you could save a few bucks and just hang your baby from that coat-rack thing like John Biggs does, but his wife banned him from ever leaving the house again.
Bonus caption contest: tell us what each of those babies are thinking. Winner gets an autographed photo of Biggs on the toilet.
