What's the funniest song you ever heard?

It's a toss up between "I like" by Heathen Dan and "Paralyzed" by the The Legendary Stardust Cowboy.

there's that old camp song that began with
"Hello mother hello father, hear I am at camp granada". I don't know who sang it but it was super funny.

Dread Zeppelin - The theme of Gilligan's Island sung to the tune of Stairway to Heaven

Honorable Mentions:

Frank Zappa - Tinsel Town Rebellion,
Allan Sherman - The Rebel, 12 Days of Christmas, Al & Yetta,
Sarah Jachman

Remember when you ran away and I got on my knees and begged you not to leave because I'd go berserk?? Well...
You left me anyhow and then the days got worse and worse and now you see I've gone completely out of my mind.. And..
They're coming to take me away, ha-haaa!!
They're coming to take me away, ho-ho, hee-hee, ha-haaa
To the funny farm. Where life is beautiful all the time and I'll be happy to see those nice young men in their clean white coats and they're coming to take me away, ha-haaa!!!!!

You thought it was a joke and so you laughed, you laughed when I had said that loosing you would make me flip my lid.. RIGHT???
I know you laughed, I heard you laugh, you laughed you laughed and laughed and then you left, but now you know I'm utterly mad... And..

They're coming to take me away, ha-haaa,
They're coming to take me away, ho-ho, hee-hee, ha-haaa.
To the happy home. With trees and flowers and chirping birds and basket weavers who sit and smile and twiddle their thumbs and toes and they're coming to take me away, ha-haaa!!!

I cooked your food, I cleaned your house, and this is how you pay me back for all my kind unselfish loving deeds.. Huh??
Well you just wait, they'll find you yet and when they do they'll put you in the ASPCA, you mangy mutt!!! And...

They're coming to take me away, ha-haaa.
They're coming to take me away, ho-ho, hee-hee, ha-haaa.
To the funny farm, where life is beautiful all the time and I'll be happy to see those nice young men in their clean white coats and they're coming to take me away, ha-haaa!!!
To the happy home, with trees and flowers and chirping birds and basket weavers who sit and smile and twiddle their thumbs and toes and they're coming to take me away, ha-haa!!!
To the funny farm, where life is beautiful all the time... (fade out)

Hey, buddy!
Yes officer..
You a head?
No, but I'm catching up, ha ha ha....

Dr Hook And The Medicine Show had an album with lyrics by the late, great Shel Silverstein of Playboy Magazine and children's book fame. Titles included "Freakin' at the Freaker's Ball", "Penicillan Penny", "Acapulco Goldie", "Roland The Roadie And Gertrude The Groupie", "Get My Rocks Off" and "Cover Of The ROlling Stone". Very funny stuff and the recording is top notch.
