Rob was just reminscing about Libby the Kid, the cowboy that hawked Libbyland dinners.
I only know these dinners from "Mystery Science Theater" riffs, although I remember the canned veggies, and the "If it says Libbys, Libbys, Libbys, on the label, label, label, you will like it, like it, like it, on your table, table, table..." jingle. Man, if anyone can find that online, post it in the comments. I'm dying to hear it again.
In its place, a really odd Libby's ad featuring Tony Randall as a guy about to be tortured by being forced to eat inferior canned veggies (contradiction in terms, no?), but no jingle.
