For some reason I was hanging out with Too Strong Dave out by Echo Cove in Joshua Tree. He starts up Effigy Too ropeless, and without giving it a second thought I followed up behind him.
When he got to the exit move, with me about a body length below, he very convincingly pretended to slip and begin to fall. Yikes! That really got my attention. We laughed it off but I didn't follow him up any other routes that day...
