I find that I am going through a phase of creative thoughts. All are practical but weird. Any further ones to add?
My latest three are:
Topless Dentistry (it came from a dream about a local MILF, long story)
Status Quo classics as performed by Placido Domingo and the RPO (sing Rocking All Over the WOrld to yourself in the style of opera and you will see where that is going. I think it works quite well and was singing it in the car earlier, so there's my proof)
Competitive sock pariing as a fund raiser for the PTA. Bring along all your odd socks and see how many pairs you can make. It would be called Socks Reunited.
There could be money in this!!
