An elephant, an engineer and a mathematician

[jack]

For sunflowerinrain and the nice librarian in the black dress I can't remember the name of.

An elephant, an engineer, and a mathematician walk into a building and the mathematician says "If two people leave, the building will be empty again," and the engineer scratches himself with his tusks and trumpets loudly.
