Old one this . . .
A small UK airline was operating a charter for oil rig workers returning from the rigs. One guy boarded the aircraft at Aberdeen with a bucket of shellfish he had caught off the rig. Obviously they would not fit in the overhead locker so the air hostess stowed them at the front of the aircraft.
As they were taxiing on to stand she could not remember which passenger had given her the bucket. So, she made the following PA:
"Would the gentleman who gave me the crabs in Aberdeen please press his call button!"
Beat that . . .
