8 pm: Television

Grab a bowl of cereal, pop the top off a Snapple and settle in for the Sein-off everyone will be talking about ad nauseam the morning after. Can this baby swim? Or was all the extravagant hype much ado about nothing? To find out, tune in for the cluster of classic “Seinfeld” clips and stick around for the much anticipated series finale, when that self-absorbed, fearsome foursome of Jerry, Elaine, George and Kramer giddy-up one last time. Earlier in the day, the Museum of Television & Radio in Beverly Hills will be screening the “Seinfeld” pilot. Be there or get out!

* The “Seinfeld” clips begin at 8 p.m., with the finale starting at 8:45 on NBC (Channels 4 and 36).
