While filming SEINFELD's "The Marine Biologist" episode, the writers felt the ending didn't work, and last minute realized they could connect Kramer's storyline of hitting golf balls into the ocean and George's storyline of attempting to save a beached whale. At 2AM, they wrote Jason Alexander's speech that would close out the episode, and handed it to him the following morning, thirty minutes before the scene would have to be taped. Alexander said "No problem", quickly memorized the dialogue, and nailed the scene in one take 🔥 it's still absolutely insane he never won an Emmy for playing George Costanza
