Sorry, I can't think of any ABers for the trapeze act. Such people have to be able to repeatedly swing from the left to the right but we seem to have only got people who're perpetually on the left or perpetually on the right on this website.
Clowns are often said to be people who're sadly misunderstood, so perhaps Peter Pedant could join their number?
By the nature of what we do already, I reckon that any of the moderators could be given the task of clearing up all of the *** left in the ring by the other acts ;-)
