Yeah. They sold it at the local Fred Meyers near my house for awhile a few years back. It's a knock-off, not actual Lava Lite. I would've bought one if it was shaped like the lava lamps, but if I remember correctly it was square.
Dunno about "Got milk?", but yes, there's that milk bottle lamp. And yes, there was an OJ one (the rounded square bottle does look like a milk or OJ bottle) and a ketchup one - not Heinz, just "ketchup" (the rounded square bottle does NOT look like any ketchup bottle I've seen, but what d'ya expect, for generic-brand? ...I mean both generic-brand lava and generic-brand ketchup)
Jonas you crack me up! Believe it or not, other than spare parts and a some duplicates (for future trades), all of my lavas and glitters are now out and on display. You know you're invited whenever you're in the neighborhood.
