Wouldn't that just be the bee's knees
You could have a TH after the bee and an arrow pointing down. I don't know what is bee-knee-th, but I suppose it is two feet down.
Actually, when I was doing the tile work on the bee in my picture, one of the blokes wanted a V in front of it to spell VB, the variety of beer he medicates himself with, but I objected.
When is your next birthday Sean? Are you going to have another one this month?
