Don't joke about bombs in the line for airport security or about Ebola while sneezing on a plane
On US Airways flight 850, traveling from Philadelphia to the Dominican Republics Punta Cana, a passenger with the sniffles let one fly.
Then, the man allegedly made a comment about his Ebola acting up.
Two hours later, the man didn't have a single friend left on the airplane.
The flight was grounded until a hazmat-suited emergency team could remove and isolate the passenger, who was found to neither have traveled to Africa, nor Ebola-infected.
