Jon Stewart does some constitutional math:

"...from Texas Senator Republican John Cornyn, who in a speech to the Conservative Heritage Foundation this week put the gay marriage issue thusly: 'It does not affect your daily life very much if your neighbor marries a box turtle. But that does not mean it is right.' Now you must raise your children in a world where the union of a man and a box turtle is on the same legal footing as man and wife. So, to sum up, it will take 2/3 of both Houses and 3/4 of the states to approve an amendment saying that two straight parents is greater than one straight parent, which is still greater than two gay parents, which is equal to a guy screwing a turtle."
