In the HVAC shop I apprenticed in, the joke was when a customer ask what size of air conditioner they needed … " 3 - 4 ton, whatever it takes" was standard response.
We also had a print out with 3 house shaped cut outs labeled 2 ton, 3 ton and 4 ton. The instructions were that you pace out from the house 100 ft and whichever size cutout the house fits into was the size AC that was needed.
This is a obvious joke that most customers did not understand without explaining it but us techs thought it was hilarious.
Also Micheal Keaton is still the best Batman.
