File this one under: Learn something new every day. From an interview with Karen Masterson, owner of Johnny’s Luncheonette in the Heights, the Boston College news site:

Karen’s sister, Wendel Meldrum, played the Low Talker on Seinfeld, a character memorable for her extremely quiet voice. Karen said Seinfeld’s infamous diner, where countless scenes are shot, is part of what inspired him to open Johnny’s.

“There was this funny Seinfeld connection too, which was hilarious,” she said. “So I asked the previous owner why he decided to open a diner at the age of 40, because usually people aren’t jumping into the restaurant business at 40. He said he was such a Seinfeld fan that he wanted to open a diner. And I said well this is perfect, because … my sister was the actress that played the Low Talker. And I thought, what are the chances that we have this bizarre Seinfeld connection? So it just felt like it was meant to be.”
