* "Laverne and Shirley - 1976" suggests you're looking for a specific release date for the TV show. However, "Laverne and Shirley" premiered in 1976, not a specific episode.
* "Squiggy in Love" is the title of an episode.
* "4-20" could be interpreted as April 20th, but it's unclear if it's a specific date you're looking for.
To answer your request, I need more context.
Please clarify:
* What exactly are you looking for? Are you asking for the original air date of the "Squiggy in Love" episode, or something else?
* What does "4-20" refer to? Is it a specific date?
Once I have clearer information, I can help you find the release dates you're looking for.
