Here's a project for the Guitar Players!

Nice, except my grandson would be aiming for the sound hole, though he does seem to aim for an imaginary and moving one already.

Could work. I've been known to play a tune or two on the throne.

Not sure that'd work at our house, since we always keep the lid closed on our toilets. Keeps the dog from drinking out of the toilet, and it also keeps things fair in the "seat up/seat down" debate. With the lid closed, both sexes have to do something before using it. Nobody gets free ride. (Although that debate doesn't really happen in our house anyway, because we both have our own bathrooms.)

I think it doesn't suit the place; a guitar is a string instrument not a wind one, which is the music that is usually played on that place
