I once worked for a company that used so many acronyms that I created an acronym for the acronyms. Without my cheat sheet I would have been lost.
I've always thought of acronyms as annoying, but recently I've discovered that they can also be EFIN funny, too! And this coming from the venerable and oh-so-serious IRS. EFIN stands for electronic filing identification number. You need this EFIN number to file your EFIN taxes.
No EFIN joke!!
