There's a Broadway show currently playing called The 25th Annual Putnam County Spelling Bee. As part of each performance, at least one person is summoned out of the audience to become a participant in the on-stage spelling competition and whenever possible, it's a celebrity.
At the January 30 performance, one of the audience members who was dragged up on stage was Julie Andrews, and they gave her a word that she had to spell. The word was "supercalifragilisticexpialidocious." To her eternal shame, she got it wrong.
