Bost, the Smoker's Friend. No idea what "Bost" was supposed to suggest. No one ever told me my teeth were downright bosty after I left the dentist's office.

Oh, hold on! Beware of Smoker's Teeth! That's it!

Yes and no. That was a slogan, but the man who invented the stuff was William D. Bost, and by gum the world was going to know it.

Get it? By gum? Sorry.
