On last night's The Colbert Report sex advice columnist and It Gets Better founder dropped by to discuss whether or not monogamy is a requirement for marriage. This issue has come up quite a bit lately ever since Savage was profiled in the New York Times and argued that sometimes monogamy is what dooms a marriage. Naturally, this has been translated by many on the right as gay people "wrecking" traditional marriage.

As usual Dan does a fine job making his point. And he gets off one of the best one-liners ever. It's so good, he actually makes Colbert break character.
