Costanza obviously has a million one liners and "Costanza" moments - what is one that makes you laugh every time that you usually don't see mentioned? I'll start:
When he greets the shipwreck survivor by saying "Ahoy!" 🤣🤣🤣
Not a one liner but the scene where Jerry's door is open and George walks right in. Jerry turns to see George just standing there and asks him how he got there. George does the 'I Dream of Jeannie' motion and blinks his eyes.
To this day, I still use this from time to time as an answer to questions.
