A list made famous from the TV show "How I Met Your Mother" inspired by Danny Glover's charater Roger Murtaugh in the movie series "Lethal Weapon."

Murtaugh's catch phrase in these movies was "I'm too old for this shit"

Putting something on the Murtaugh List acknowledges that as you grow up, there's stuff you just can no longer do that you did in your youth.

I can no longer pull an all-nighter. It's on my Murtaugh List.
