The dollar values are NOT for the lamp. lol
Check this out from Storage Wars:
I've seen a few on Skins. (Acouple of Lava Lite premiers, an astro, some kind of rocket).
not sure if this counts, but i have got a lava lamp on the top of my tv, so in effect it is a lava on tv
The series One Tree Hill has them troughout the whole series.. Heres a clip
The uncle they are talking about in this clip, had a giant, but havent been able to find a clip showing it..
And a place in the series called Karens Café had around 10 lamps scattered around in the café... Just cant find any clips of it.. :(
