The episode of "I Love Lucy" is the one where Lucy, Ricky, Fred, and Ethel travel to Cuba after their vacation in Miami, FL. In the nightclub scene, where Ricky and Little Ricky are doing the Ba-Ba-Lou number, Ricky's Uncle Alberto gets so excited that he starts pounding on his hat, subsequently smashing it.
In the next scene, where he is telling Lucy that anyone who can have a son like Little Ricky is OK in his book, a perfect, unsmashed hat can be seen on the table in front of Uncle Alberto
