Jon Stewart Responds to Rick Santorum's Fear of Mislabeling Napkins 

Jon Stewart took on Rick Santorum for his growing list of strange similes for gay marriage.

Stewart noted that the Republican presidential candidate had taken a turn as a "motivational food court speaker" and said during a stop at an Iowa grocery store that calling the relationship of two men a marriage is like calling a napkin a paper towel.

"His point is well taken," Stewart said. "It's the slippery slope argument. If people start using paper towels as napkins, what's next? Sleeves, drapes, mouth-on-dog wiping? Moral chaos!"
