Lizards communicate by doing push-ups

Just like that guy who spends way too much time and is way too loud at the gym, lizards do push-ups in an attempt to attract a mate. Researchers found that four species of male Jamaican lizards - called anoles - greet each other every dawn with a display of push-ups. This is to warn other males of their species to back off and to attract females. They do the same ritual at dusk before heading in for the night.
