According to news sources, he was pulled from his flight in England’s Manchester Airport before scheduled take-off for Philadelphia. This has happened before, and if you’re ever a passenger in the same situation, here are some clues to listen for when you hear the captains’ announcements:

All passengers fasten your chastity belts
The attitude will be very high, but not as high I am right now
This flight is headed for some place I can’t remember
I just got slapped for explaining the word cockpit to a stewardess
Damn service dogs! I just slipped on something in the aisle
Be kind to that sloppy drunk in the next seat. He’s my drinking buddy.
