Was it a Titleist ???
Based on my recall of that Seinfeld episode it was indeed a Titleist.
This was also the episode where George told his girlfriend he was a Marine Biologist. Then later in the episode when they are walking on the beach they come upon a beached whale.
Then one of the people in the crowd yells out, “is anyone a marine biologist?”
Of which George’s new girlfriend responds yes. Putting George in a precarious situation.
Of course, they soon discovered that the whales issues was a Titleist golf ball stuck in its blow hole.
They just do not write comedy shows like that anymore.
