Ladies and gentlemen, I give you... The Irv.
Apparently some Chinese company is trying to sell this "retro" clip on cell phone accessory. It actually sounds kinda neat, extended battery life and what not.
As a matter of fact, this could seriously be Irv's actual alternative to trying to replace his current phone (which is dying), and as fate would have it I've been tasked with finding a suitable replacement.
I assume the bigger the better. I'm sure if he had things his way, he'd want an extra large clip on to go over the Zack Morris phone he has now.
