On this week’s What's Trending live show, we have the father of viral parodies "Weird Al" Yankovic talking about how he took on the Mother Monster, Lady Gaga, with his song "Perform This Way." We also have Mashable's editor in chief Adam Ostrow and the host of NBC's "Poker After Dark" Ali Nejad discussing the top trending topics of the week from Justin Bieber wearing Tiffani-Amber Thiessen (who is wearing Justin Bieber) to the death of print media to Supreme Court ruling that violent video games are protected by the First Amendment.
