1000 Push ups per day

[imthaifool]

I have a friend who claims he used to do 1000 push ups a day. He is quite strong for his size, but I felt like he was exaggerating. I called him out on it and he defended his position. I still don't believe him. What do you guys think? Do you know of anyone who can or does a 1000 push ups a day? Is it even possible for an average person aka not a body builder or fitness freak. Even people in jail don't do that many push ups.
