Bill Kristol is such a trooper:

“Neoconservative journalist and commentator William Kristol was about 30 minutes into his speech on international affairs when a slender young man crossed the stage and slung the ersatz pastry into his face…Kristol appeared momentarily stunned, then wiped the brown and white goo from his eyes with a paper towel, stepped back to the podium and said, ‘Let me just finish this point.‘”

**Update: Pat Buchananis not a trooper:

Pat Buchanan was forced to “cut short an appearance after an opponent of his conservative views doused him with salad dressing,” the AP reports.

“After he was hit, Buchanan cut short his question-and-answer session with the audience, saying, ‘Thank you all for coming, but I’m going to have to get my hair washed.’”
