There was the famous case of a certain 'remark' being inadvertantly transmitted on the ATIS about an inbound flight to a large Scottish airfield. (It involved the word 'fxxxing')
Then when I retired from ATC at Farnborough and started FISOing from Fairoaks less than 2 weeks later, a lot of pilots found it confusing hearing my voice saying they thought they had the wrong frequency selected!
