On the subject of vending machines, in the day the sports coaches were the sole operators of any vending machines, probably to fund sports. For 50 cents you could get a cup of a cold beverage from whichever vendor kicked back the most money to the team.
One day the regular soda machine was replaced with a ZIMI machine, a slushy ice beverage.
Each time it dispensed a cup it told a joke, which it then laughed at.
(

only page on the Internet that remembers what a ZIMI machine was, and who the joke teller is.)
Well, the jocks immediately started pounding on the machine every time it laughed.
That machine got the snot kicked out of it. You'd hear a joke starting to be told, then
wham, wham, wham!, as a jock came from nowhere to wale on the machine.
The coaches tried yelling at everyone to not beat on the machine, but that didn't work very well.
In short time it had become a running sport to buy a drink and wale on the machine.
Even the nerds would give it a kick.
People would also beat on it when they didn't get a joke with the drink, but that
was somehow not as rewarding as beating on a machine telling you a bad joke and
laughing at it.
I think the fourth time or so it broke down from abuse the coaches pulled it and put
in a non-verbal machine, then sent home the next few people who tried hitting that machine.
