Gummy Ears

A Kerryman on his first aeroplane flight was offered some chewing gum by the stewardess.
'What's that for?' he asked.
'It's to protect your ears during take-off, she replied.
Some time later she asked him how he was feeling.
'What's that?' he said.
'How are you feeling now?' she shouted.
'I'm sorry', said the Kerryman, 'I can't hear a word you're saying with all this chewing gum in my ears'.
