A joke

I heard a joke that cracked me up yesterday on the Howard Stern Show.
They’re talking about the Foo Fighters song that goes “There goes my hero…” and how Howard’s Hero is his Dad, and what person is who’s hero etc…

And Artie Lang goes: “Reminds me of a joke… You know when I was growing up, I thought my dad was just the best, he could do anything. He was Superman. But then, I grew up, became an adult, and noticed that my dad was nothing but a drunkard who liked to wear a cape.”
