Many people watch the Super Bowl for football. Others watch for the commercials, which can be entertaining and educational. This year, one commercial highlights deaf culture and humor. 'Bob's House,' a Pepsico commercial, is based on a popular joke in the deaf community. It was created by a group of Pepsico employees, and Chicagoan Darren Therriault is both a Pepsico employee and actor in the commercial.
