This one made me chuckle:
Snickers launched in the UK in 1967, but before consumers could get their hands on it, it went through a change of name — because Snickers was deemed too close to another, saucier, word.
“Knickers”, I assume. Not that I think that that name is “saucy”, or anything like it. “Knockers”, maybe?
On the bright side, imagine the fuss today if someone tried to launch a snack bar called “Sniggers”… and it was made of dark chocolate. I imagine that Sniggers having been rejected, one could try “Darkies”, then?
