In this episode, Josh has lots of triathlon questions for Mike, who has recently been trying to convince Josh they should do one together. Josh announces he has finished his requirements for his Mastership in the Academy of General Dentistry, and Mike is duly impressed as Josh must be one of the youngest dentists to accomplish this. He is certainly he sexiest! The guys discuss pre-made composite veneers and how much they hate this concept. Josh gets Mike to spill the beans (and a yam) regarding what happens when nature calls during a run, one of Josh's biggest fears.
