I'm really suprised that something so "pro-drug" got on TV. I don't think it would happen these days. It definitely not politically correct.
The song is from some musical (I can't remember which one) and I thought it was kind of fun, in a campy sort of way. The conceit of the number - that this was a discussion they held throughout the course of an date - was sort of funny. It would sure make for a long evening ;-)
I miss the old variety show stuff. The modern equivalent (American Idol and such) is too screechy and over-produced. Say whay you will about Bea and Rock, but at least they could sing. No synthizer fill-ins or redubs for them.
