In this vintage McDonald's commercial from the early eighties, Ronald McDonald, Grimace, the Hamburglar, the Fry Guys, Birdie, and some creepy dude called The Professor play a bastardized version of baseball before giving up and heading over to Mickey D's for assorted fried and processed chicken parts. The characters are quite creepy; no wonder my entire generation has grown up to become horrified by clowns and large purple things.
In this fraudulent excuse for 'baseball', The Professor uses a non-regulation bat that totally ruins the game, so obviously this commercial is an allegory for the upcoming steroids drama that haunted baseball for years.
To wit:
For a second, non-embeddable commercial where Ronald McDonald actually plays with his food, check out this clip featuring the McNuggets and a ton of bad baseball puns.
This commercial is older than Jason Heyward
