"Barely Legal Pawn Shop" Emmy promo: Their meth-dealing days may be behind them, but that doesn't mean Aaron Paul and Bryan Cranston have lost their knack for playing shady entrepreneurs. In this hilarious promo for the Emmy Awards (which air on Monday, August 25), the Breaking Bad stars team up with Julia Louis-Dreyfus, who's trying to pawn the Best Supporting Actress award she won for Seinfeld because she got drunk and bought an island.

America's Got Talent rock cellists: It's the Rolling Stones' "(I Can't Get No) Satisfaction" like you've never heard it before, thanks to rock cellist duo Emil & Dariel, brothers who have reached the quarterfinals on the current season of America's Got Talent.

Jimmy Fallon and Pierce Brosnan play "Goldeneye": See Jimmy Fallon in ultimate fanboy mode as he plays "007 Goldeneye" on Nintendo 64 with his Tonight Show guest, Pierce Brosnan.

George W. Bush's Ice Bucket Challenge: Unless you've been living under a rock, you've probably heard about the Ice Bucket Challenge, the social media campaign designed to raise awareness of ALS (Lou Gehrig's Disease). Celebrities and non-famous folks alike have been participating by dumping buckets of ice water over their heads and challenging other people to do the same. Here, former President George W. Bush accepts his challenge, with a little help from his wife Laura.  

Ben Affleck's Ice Bucket Challenge: President Bush isn't the only person who enlisted his spouse to help with the ice bucket challenge. After being challenged to participate by Tyler Perry, Ben Affleck got doused — perhaps a little prematurely? — by his wife Jennifer Garner, whom he promptly tackled and threw into their swimming pool. As a bonus, you can hear one of their kids adorably laughing in the background.

Taylor Swift's "Shake It Off": The queen of country goes pop with the video for her latest single, "Shake It Off." The song is from her forthcoming album 1989, which is due to hit shelves on October 27.

Nick Offerman's Shower Thoughts: Nick Offerman offers deep musings and poignant factoids on a variety of subjects in this thought-provoking video, including the fact that "Once you have a Ph.D., every meeting you go to becomes a doctor's appointment."
