The former Seinfeld star on Thursday shared a photo of a balding mannequin dressed in white briefs and a tank top that looked suspiciously like himself.
"Don't know who made these mannequins. But if anyone puts glasses on the one 2nd from the left, there will be a lawsuit," Alexander wrote.
The mannequin's white undergarments conjured up images of a Seinfeld episode in which Alexander's character, George Costanza, posed for a photoshoot wearing nothing but white underwear and black socks.
Fans of the show were also reminded of an episode in which Julia Louis-Dreyfus' character, Elaine, found her own mannequin look-alike.
