5. Tickle Me Elmo
This toy looks much worse given recent events, but it was still pretty stupid to begin with. Anyone who was too old to be bought a Tickle-Me-Elmo in 1996 remembers the hysteria surrounding the laughing, shaking toy's release. A Wal-Mart employee was legendarily trampled during the '96 holiday season for making the mistake of holding a box of Elmos within reach of ravenous crowds.
Later releases "Tickle Me Extreme" and "LOL Elmo" attempted an updated (kinda pathetic) twist on the doll, but neither spin-off produced the insane demand of the original doll.
