An engineer, a mathematician, and some other geeky type are sitting outside a building. They see one person walk into the building and two people walk out, and they each explain it differently.
And it’s really funny and I don’t remember anything about it besides that.
After seeing the two people walk out, he says, “If one more person walks in, the building will be empty.”
I think though, that you’ve got two jokes conflated…the other one I’m thinking of is where the engineer and the mathematician are each trying build a fence to enclose the largest area.
There’s always this one that sounds similar:
A biologist, a physicist, and a mathematician are sitting in an outdoor cafe. They watch two people go into a building across the street. Shortly thereafter, three people come out.
“Hmm,” says the biologist. “It looks like they reproduced.”
“Nah,” says the physicist. “There was obviously error in our initial measurement.”
The mathematician looks up from his coffee. “Who cares? If another person goes in, it’ll be empty.”
How does a mathematician make ice cubes with boiling water ? He takes the ice tray out the fridge, pours the water in, lets the tray sit in the freezer for 30 minutes.
How does a mathematician make ice cubes with cold water ? First he heats it to a boil to reduce the problem to a known one…
Thank you, thank you, I’ll be here all week, tip your waitress !
An egg farmer wants to increase production. He hires a nutritionist, a mechanical engineer and a physicist.
The nutritionist explains that the farmer needs to increase the amount of protein inthe chicken feed and provide vitamin enriched water.
The mechanical engineer shows elaborate plans for chutes and ladders designed to gently deliver the eggs from the nests to the inspection area thereby reducing breakage.
The physicist pulls up a chalkboard and declares “OK, first, assume a spherical chicken…”
I told this to two of my brothers-in-law, one an artist, the other an engineer…guess who laughed and who stared.
