This really appeals to my twisted sense of humor, and while you could argue that someone may have too much time on his/her hands, when the result is as funny as this, I say that's not such a bad thing. (besides, it beats the hell out of 90% of the status updates on FB...which means 90% of people have too much time on their hands and aren't funny to boot).
I like the acrobats (acroflies?) with the one being flipped from the teeter-totter. I would caption that one, "The Flying Wallendas." :D
Once I get past the "omg, these are dead flies" issue, I laugh out loud at these. I love the flies waiting in line for the restroom. The fella with his arm raised cracked me up. (To be realistic, there should be more flies on the women's side than the men's.)
