Grab a glass of milk, peanut butter lovers, 'cause today host Marc Summers is spreading it on thick. First, we'll see what's shakin' at Reese's, where they turn piles of peanut butter into their famous cups. Then, it's off to Late July to see just how their pint-sized sandwiches get stacked up. If gourmet is your way, then you'll love PB Loco, a restaurant that caters to the PB adventurer, or you can keep it old school with the darling of peanut butter bites, Mary Jane.
