Norm's Lava Lamp is a magical lamp where Norm the Genie resides when he has no master to grant wishes to.
It made its first appearance in the episode, "Genie Meanie Minie Moe". Timmy found the lamp, which was sold to him at a "garage sale" by Mr. Birkenbake, and rubbed the dust off it, releasing Norm. This was Timmy's first encounter with Norm. When the person who has Norm makes his third and final wish Norm is forcibly sucked back into the lamp unless there's another source of magic (for example, Cosmo and Wanda in Genie Meanie Minie Mo) closer to the lamp than Norm is. If so, then the other source will be sucked instead and Norm will be free. Often, this wish is "I wish I'd never met you", or "I wish everything was back to the way it was before I found you." Chester McBadbat was the last one who had possession of the lamp. When Chester wished for everything back to normal, Jorgen Von Strangle took the lamp so he could use it as a urinal cake. It is presumably still in his toilet as of now if he did not get rid of it yet.
