We've got a record breaker of a show today! "Cake Boss" Buddy Valastro sees how many cupcakes he can frost in one minute in an attempt to break a Guinness World Record. Then, one half of DIY duo "The Cousins," John Colaneri, hammers hard for his record. And we're meeting wild animals that hold records of their own! Plus, Rach is making a cozy grilled cheese with sundried tomato spread, and red cabbage soup.

We're putting three couples to the test in our latest "Human Lab," trying products that claim to cure some of their partners' biggest pet peeves — including our pal Bob Harper, who's testing out a gadget to help him stop losing his glasses. Plus, Aldis Hodge is in the house dishing on his new movie with Taraji P. Henson!
