HISTORYCHANNEL

Adam and Rob serve up their most annoying stings in the history of the pain index.

Kings of Pain

Cocktail of Venom

It's America vs. Australia in a battle royale of pain administered by sharks; after getting stung by both, Adam and Rob realize that when their countries win, they lose.

Stinging Sharks

Rob and Adam test the yellow head moray eel for possible venom effects but must resort to a risky, bloody bite; venom is not the issue for the electric eel.

Eelectrocution

Rob and Adam test the pain dished out by a trio of unlikely creatures commonly kept in home aquariums; they proceed to ruin the image of a popular cartoon movie character for millions of children.

Aquarium Nightmares

Some of the most painful animals around can be found in the backyard; Rob and Adam take on an assassin bug, a Jerusalem cricket and the brown widow spider, producing a record-setting episode of pain.

Backyard Beasts

Adam thinks he's getting his revenge on Rob for selecting tarantulas earlier this season by programming Rob's phobia: centipedes; the joke is on Adam when an American centipede produces one of his most painful bites ever.

Hundred Tiny Screams

In a tribute to the godfather of the pain index, Dr. Justin Schmidt, Adam and Rob tangle with a new batch of extremely painful and deadly insects; one colony of ants kicks the Schmidt out of them.

Schmidt Happens

Adam and Caveman Rob get bitten by one lizard whose venom is in doubt, but not its ability to latch on and tear flesh, and another whose venom is notoriously painful; the shocking results set new records for the pain index.

Big Biting Lizards

Adam has a phobia of tarantulas, so Caveman Rob picks two of the world's nastiest ones for them to endure, including a tarantula with the well-deserved nickname of "Orange Bitey Thing."

Arachnophobia

Adam and Caveman Rob take on America's biggest and most deadly scorpions, but the surprising result is a hugely painful wake-up call, and a new Scorpion King is crowned.
