Is "Blackbird" the worst Beatles song of all time?

Don't get me wrong... I love the Beatles, but I heard this song for the first time in years the other day and started cracking up. IMHO it's the dorkiest song they ever did. Part of it seems way off key. Ok, they're the Beatles, they can get away with that. But imagine some dweeb doing this song on American Idol... especially the bird chirping part...:)
