This Seinfeld t-shirt features the logo for Mandelbaum's Gym. The logo includes the gym's tagline, "It's Go Time Butterbean."

Three generations of Izzy Mandelbaums all shockingly looked the same age. When the three men weren't working at their Magic Pan restaurant, they were at the gym, becoming the most physically fit men at the Del Boca Vista retirement condiminum complex in Florida.

You'll have everyone saying "Mandelbaum! Mandelbaum! Mandelbaum!" when you wear this Mandelbaum's Gym Seinfeld T-Shirt!
