Every year Solstice run a Halloween Scavenger Hunt. The idea is for their authors to place a riddle or a joke on their website, or blog. Those participating then have to find each in turn. There are three prizes for correct entries:
3 winners
All have to have the correct answers of course.
First place – gets 50 of our ebooks
Second Place – gets 5 of our ebooks
Third place – gets 3 of our ebooks
So what’s my funny?
I opened my wheelie bin this morning and a wasp flew out. What kind of sick person throws a wasp in a bin?
