It may sound like a bad joke from a family comedy film, but this actually happened: Michael Doyle, a 19-year-old who suffers from Tourette's syndrome, was prevented from boarding a plane for involuntarily ticking the word "bomb." According to Doyle, he was waiting to board his flight to Puerto Rico when he suddenly found himself repeating the "B word" while having a panic episode over the recent terrorist bombings in Boston, Massachusetts. In responding to the news, Jet Blue released a statement explaining that Doyle had been deemed a "safety concern" by the plane's commanding pilot and the airline offered him a free round-trip ticket to make up for the embarrassing fiasco.
