Tina Fey's no-show wasn't the only last-minute change from Lindsay Lohan's critically disappointing (but ratings triumphant) Saturday Night Live appearance last weekend. TMZ reports a sketch was cut after dress rehearsals in which Jon Hamm, who was on hand for the telecast but woefully underutilized, played John F. Kennedy to Lindsay's Marilyn Monroe. In the sketch, Andy Samberg played Rick Santorum, who, while speaking at a conservative event, is visited by a vision of the movie star and president paramours. They explain that Marilyn was using birth control pills made available to her by Medicare -- a revelation that causes Santorum to "vomit uncontrollably." (That's a wink to Santorum's comments about how JFK's speech about keeping religion out of politics made him "want to throw up," in case you missed it.) TMZ says the sketch was pulled at the last minute for "time restraints." Considering what did make it to air, the sketch must have either been painfully unfunny, or just too controversial in light of the growing Rush Limbaugh/Sandra Fluke controversy. Or perhaps it was just a matter of the vomit-spewing mechanism malfunctioning that night. That's live TV for you.

In other Hamm news, the Mad Men star has strong words for two of our culture's most, uh, recognizable faces, in an upcoming interview in Elle UK magazine. 

Via Access Hollywood:

“Whether it’s Paris Hilton or Kim Kardashian or whoever, stupidity is certainly celebrated,”

“Being a [expletive] idiot is a valuable commodity in this culture,” he continued. “You’re rewarded significantly.”

We'll assume he holds Lohan in a much higher regard.
