Meaning of "Mr Right's first name is Always"

What does this quote mean?

When I eventually met Mr. Right I had no idea that his first name was Always.

— Rita Rudner

Solution 1:

It's a joke. It's common to talk about "Mr. Right" ... meaning, the ideal man for marriage.

On the other hand, people who are "full of themselves", who talk too much, who always think they know best ... they have an "I'm always right" attitude.

Note that if your name was "Something Right" (say, John Right, or Joe Right) ... it's a bit like that: first name is "Always" ... "Mr. Always Right"

So, it's a joke.

Solution 2:

When Rita first met the man, she thought he was perfect ("Mr. Right"). Later she realized that he thought so too. He's a know-it-all, he thinks he is always right.
