Rachel Maddow seemed to have a good time on her Monday MSNBC show going through some of the bigger pranks companies played on people on April Fool's Day.

She said she knew that YouTube revealing that the site was really just one big contest and Google's ridiculous new product "Google Nose" were totally jokes.

But Scott Brown guest-hosting Bill O'Reilly's 8:00 p.m. show on MSNBC? She said she totally fell for that. "I totally thought that was a real thing. For a second. It's amazing," she said. Scott's guest-hosting gig on Fox News was not a joke. He actually did fill in for Bill O'Reilly on Monday night. Maddow found this laughable, probably because of her storied past despising the former Massachusetts senator.

She described Brown as "the man who bragged about meeting with kinds and queens. The man who became Twitter imortal with 'Bqhatevwr.'" She added, "Scott Brown - known for being a lot of things -- but never especially known for being all that great for the communication part of telecommunications."

April Fool's Day is also Maddow's birthday.
