Doug Henning
It is a variation of the Houdini, except instead of a guy doing a girl doggy style, its a guy doing another guy doggy style, and therefore qualify as a gay sex act thus the name Doug Henning in lieu of Houdini.
Did you hear about Rik? Apparently he gave is male lover the ol' Doug Henning last night. I'm just glad he did not tarnish a good name by calling it a Houdini.
