Did this ProBlogger Really make $100,000.00 a month from AdSense?

saw on another forum where there was a picture of this guy with a check for 1 month of adsense revenue of over 100k! Do You people think this is possible or is it fake or mebe even he let his revenue build to get 1 big check? I was originally inspired by problogger.net when he said he made 100k/year! I make about 1,000$ a month and feel I am doing well. Its nice to think $100,000.00 A MONTH is possible.
