Toaster (Fallout 3)

There are two variants of s to be found in Fallout 3, a pre-war and a post-war version. The pre-war toaster only exists in Vault 101 whereas the post-war version is found all over the Capital Wasteland. Both versions can be bought from various shops.

The only known use for this item is to serve as Rock-It Launcher ammunition.

Trivia
After disarming the nuke in Megaton Three Dog mentions that his toaster needs repair (there is no known speech thread to repair his toaster) on the radio when describing your exploit. It may be a subtle reference to Wasteland, where the player could repair broken toasters for various items. Or it could just be a common joke.
