Jack in the Box has called out competitors such as McDonald's before in ads, tweets, and so forth. That said, this latest one is pretty clever. You can watch it here. As you see, Jack drops off some breakfast food at a mystery house and then throws an egg at the mailbox--a mailbox clearly labeled as, "R. McDonald." The well-known mascot at one point for McDonald's (I'm not sure how much he is used anymore) was the clown Ronald McDonald, so this ad is basically one mascot egging another's house. It's smart, kind of rude, and just simply funny. I always enjoy some friendly throwing of shade between these big fast-food companies, and this was a hoot to see on the television.
