Shouldn't that have been "wholly Mackerel"?
If not, then that comedy writer was asleep at the keyboard. Like the one for a really bad Leslie Nielsen sci-fi spoof where the female agent had been capture and place in a bubble-wrap outfit for transport. In the subsequent fight scene, every time she blocked a punch there should was no appropriate sound; it would have actually be funny to hear bubble-wrap popping sounds. Their creative licenses should have been revoked!
