According to the syndication schedule posted by David Jacobson, "The Gum" episode will be airing again on Feb. 3rd.
This reminded me that I've seen what appears to be the gum in question being sold around NYC's East Village, which is very near my home. The gum comes in a red wrapper with Chinese writing on it, and it has what appears to be a picture of a ginseng root on the wrapper. No, I haven't tried it, nor do I plan to.
For those who have posted questions asking whether Bosco or Drake's Cakes are real products (which they are): apparently, even "The Gum" is a real product.
Has anyone tried it?
