This symbol, the ampersand, used to have equal status with letters of the alphabet and was stuck at the end after Z.
That's how it got its name. People would say "X,Y,Z, and, per se, And". (And "sort of" an and). Thus, "And per se And" became Ampersand.

"You know, Im thinking of getting into the kitchen cabinet making business, but I don't think I'll be able to turn a profit with all the competition."
"Here, hold the bong and let me make some calls."
