If you’re a little tired of the electronic voice your GPS uses, TomTom has added two personalities to its list of celebrity voices that you may not expect.

Sesame Street’s Bert and Ernie have been added to TomTom’s list of voices you can use for navigation, including John Cleese, Billy Conolly, Snoop Dogg, Darth Vader, Yoda, Spongebob Squarepants, Homer Simpsons, Mr. Burns, and Bugs Bunny.

The Bert and Ernie voice pack does cost a few bucks, but given the entertainment value you’ll get while driving, it’s probably worth it.
