Infamous Joke

How is it that this is just now clicking with me?

My dad was fairly notorious for his outlandish jokes and comments. A long time ago some family friends lost their dad. My dad's response? "Too bad, so sad. No dad."

I just wrote an email to a friend saying "too bad, so sad." In my head I finished the statement with "no dad." When the irony of it all hit me, I laughed. I like to think that Dad is laughing with me, wherever he is.
