This qualifies for the dumbest “controversy” in a while (there is a lot of competition though) and rivals Evan Thomas’s “god” comment for it’s revelatory nature:

During an interview for CNBC at the White House on Tuesday, a fly intruded on Obama’s conversation with correspondent John Harwood.
“Get out of here,” the president told the pesky insect. When it didn’t, he waited for the fly to settle, put his hand up and then smacked it dead.
“Now, where were we?” Obama asked Harwood. Then he added: “That was pretty impressive, wasn’t it? I got the sucker.”
Friedrich said that PETA was pleased with Obama’s voting record in the Senate on behalf of animal rights and noted that he has been outspoken against animal abuses.
Still, “swatting a fly on TV indicates he’s not perfect,” Friedrich said, “and we’re happy to say that we wish he hadn’t.”
