Scotch Tape

Hey Beth, why is it called Scotch tape?

First of all, Scotch is a brand, not a kind of tape (like Kleenex and Chapstick are brands, not items), made by the company 3M.  The legend behind the choosing of the name is that one of the first iterations of masking tape was not quite adhesive enough.  The bodyshop painter attempting to use the tape exclaimed, "Take this tape back to your Scotch bosses of yours and tell them to put more adhesive on it!"
