He remembers the names of 100 women?

Yeah, the whole thing is pretty far-fetched.

While that is somewhat implausible, he didn't actually remember some. But why is it so implausible that he was with 100 women? I am not that promiscuous, but he said he got married at 40. If you think he started at 20 (which we know from the film he had his first time at 18), that would be 5 women a year for 20 years. That isn't all that crazy for some people. It sounds like a lot but he's not in Wilt Chamberlain or Warren Beatty territory by any stretch. The What's Your Number situation with over 20 people for Anna Faris' younger character is different. She was a ho. LOL
