I did one of the funniest jobs where my official title was “Christmas Tree Wrangler” (though I don’t know if it actually showed up in the credits like this).
A friend was decorating a film that needed someone to just come in, be in charge of decorating the Christmas tree. I was going on a flight the day they needed someone, so she said I could just come in, quickly lead the decoration of the Christmas tree, then go take my flight.
So I showed up early to set with my luggage, decorated the tree, and then went straight to the airport.
