Reminds me of another joke:
Researchers ask an engineer and a mathematician to both go into a kitchen and make tea, while they watch from another room. The first time, they both do it the same way:
- find the kettle, teapot and teabags, take them out of the cupboard
- fill the kettle with water and place it on the stove
- turn the stove on and wait for the water to boil
- put the teabags in the teapot, then fill it with boiling water.
Later on, they ask the engineer and the mathematician to repeat the experiment. This time, though, when they go into the room the teabags are already in the teapot and there's a pot of boiling water sitting on the stove.
The engineer pours the boiling water into the teapot and says "done!"
The mathematician puts the teabags back in the box, dumps the boiling water down the drain, puts everything back in the cupboard and says "done! I've reduced it to a previously found solution!"
