Rick Santorum—once again—compares same-sex marriage to incest.

"So when people come out and say that marriage is something else—marriage is the marriage of five people, five, 10, 20. Marriage can be between fathers and daughters. Marriage can be between any two people, any four people, any 10 people, it can be any kind of relationship and we can call it marriage. But it doesn't make it marriage."

Santorum made these comments during an extended/tortured metaphor about how marriage is a lot like a brown paper towel... which isn't a prop that Santorum's handlers should be letting him use. Almost as bad as this one.
