Video: Subway Butcher’s Thank You (Falettinme Be Mice Elf Agin)

Can someone tell me what Jared from Subway & Michael Phelps have to do with “Thank You (Falettinme Be Mice Elf Agin)” please? A “Be Yourself” ad campaign?  Flipping free advertising on my site now no doubt as well. Grr. Who’s making money off of that? Just saying.-Dr.FB
