H. John Benjamin has incredible range as a voice actor, which he has proven by playing Bob from Bob's Burgers and Sterling Archer from Archer so differently it's like they're two different people.
One is a mellow family man who owns a burger joint, the other is a drunk secret agent/detective who lives a very violent life, both with completely different voices as delivered by H. John Benjamin.
Both shows have hinted at having a crossover episode for years, and the Archer episode entitled Fugue And Riffs kinda did a crossover type thing as Archer assumed the role of Bob due to amnesia.
But until an official H. John VS H. John freak out episode airs you should watch 'I Had Something For This Burger' by artist Simon Chong of Explosive Alan. It's a real John Benja-mind bender!
