( CNN ) -- At last the mystery has been solved . Since a fan tweeted a picture of Jerry Seinfeld and Jason Alexander outside Tom 's Restaurant , which served as a stand-in Monk 's on the hit NBC show `` Seinfeld , '' there has been buzz about what it could mean . Was it a Super Bowl commercial ? Something having to do with Seinfeld 's Web series `` Comedians in Cars Getting Coffee '' ? Or was it perhaps , like the sitcom , a whole bunch of nothing ? The answer is yes . In addition to the comic , the mini- '' Seinfeld '' reunion included Alexander , who played George Costanza on the show , and Wayne Knight , who played Newman the postal carrier . It turned out to be a bit of a commercial for Seinfeld 's `` Comedians in Cars Getting Coffee . '' On that show , Seinfeld often sits down for a chat with fellow comedians and celebs . In this case , Seinfeld was in character as Seinfeld hanging out with his old buddy Costanza in search of some grub during the Super Bowl . The pair bantered about a friend 's Super Bowl party and a discussion ensued about `` over cheering '' football games . Then Jerry 's nemesis , Newman , showed up . In all , it really was straightforward . Though keep in mind `` Seinfeld '' celebrates its 25th anniversary this year , so perhaps there is something more to the mystery after all .
Fans had laughed after Jerry and Alexander were spotted together . The spot airs during Sunday 's Super Bowl . ` ` Seinfeld '' celebrates 25 years in television .
