Texas Governor Rick Perry has mocked Rick Santorum's stance on gay marriage.

The 62-year-old Perry spoke for the GOP Party at Saturday night's Gridiron Dinner in Washington, The Wall Street Journal reported. The annual journalist dinner roasts prominent politicians from both sides of the aisle.

In his speech, Perry poked fun at his unsuccessful bid to win the GOP presidential nomination.

On being the Republican front-runner: “It was the three most exhilarating hours of my life.”

“Here's the hardest part for me,” he added. “Weakest Republican field in history and they kicked my butt.”

A degree in animal husbandry may have been part of the problem, “Animal husbandry. That sounds like what Rick Santorum thinks gay marriage leads to,” he joked, referring to Santorum's 2003 comments comparing gay unions to “man on dog.”

Perry also poked fun at Mitt Romney, whose net worth is roughly $200 million, saying that standing next to him on debate stages “I kept waiting for him to say, 'Pardon me, do you have any Grey Poupon?'”

A campaign ad in which Perry laments the end of “Don't Ask, Don't Tell” inspired numerous parodies on the Internet.
