Another from the John Smiths bow-wow stable-
"Magnetize yourself with a Magnet.¬
Magnetize yourself with a Magnet.¬
If you take a glass or two,
It will cheer you through and through,
And they generally call it mag-net-izing."
¬ is a dee-dah blast on a trombone, and if memory serves the whole was repeated several times. I have vague recollection of shots of someone being picked up by a crane by means of a giant horseshoe 'magnet', also of someone juggling using club-sized horseshoe 'magnets'. Yeah, John Smiths still use the magnet symbol on their cans and (I think) also on their pumps.
Power of advertising, eh? We didn't even have a TV until some dozen years after these adds that I remember, so this is all from the relatively short exposure I got when visiting friends.
