Dad: Jerry Stiller
Son: Ben Stiller
Funny is a Stiller family trait. Jerry is best known as Frank Costanza, the father of George Costanza, on "Seinfeld." In real life, Jerry is dad to Ben Stiller, the star of "There's Something About Mary" and "Meet the Parents." Ben and Jerry appeared together in "Zoolander," in which Ben played the titular character, a clueless male model, and Jerry acted as his agent. —XFINITY Entertainment Staff (Photo by Michael Loccisano/Getty)
