Bowser & Blue: Hail to the Colorectal Surgeon
No love for Flanders and Swann?
And of course,
The First and Second Laws of Thermodynamics! (“Yeah, that’s entropy, man.”)
I don’t think I’ve seen a reference to Sandra Boynton’s albums yet, and they are more specifically children-oriented, but they are great, especially the One Shoe Blues (with BB King!).
Oh there’s tons from TV and movies too.
Simpsons: In A Gadda Da Vita
South Park: Kyle’s mom’s a bitch
Any from Sister Act 1, not 2 or 3
My Best Friend’s Wedding: I Say a Little Prayer for You
Family Guy: Rock Lobster
Most songs from Glee, but I like Safety Dance the best.
Sorry, it’s “In the Garden of Eden,” by I. Ron Butterfly. 
Some fun songs from an obscure band. . . Relient K:
Sadie Hawkins Dance
In Love with the '80’s
William Shatner’s covers of Mr. Tambourine Man and Lucy in the sky with diamonds should not be neglected.
“The Curley Shuffle” by Jump In The Saddle Band. What could be more kid friendly than a song about the Three Stooges?
ETA; “Pencil Necked Geeks” by Classy Freddie Blassy (sp?)
Not really a novelty song but my kids really loved The Yeah Yeah Yeah Song by The Flaming Lips.
The Shoop Shoop Song (It’s in His Kiss) - Betty Everett (even Cher’s version is OK)
I defy two girls under 18 YO to not launch into a Supremes shtick when this starts playing.
I Gotcha - Joe Tex
Wild Thing - The Troggs (not Tone Loc)
Bang a Gong - T Rex
Popcorn - Hot Butter
A Taste of Honey - Herb Alpert & TB
Blackwater - Doobies
I Am a Child - Neil Young
Midnight at the Oasis - Maria Muldaur
Also his cover of Pulp’s Common People which is IMNSHO better than the original.
Return of the Red Baron, Snoopy for President, and - come December - Snoopy’s Christmas.
Yellow Submarine, if it’s not been mentioned. My kids loved (and still do) that particular Beatles song.
Jim Stafford had a few funny novelty songs back in the 70’s.
Hey JLA, “Jake the Peg” is hilarious, thanks for the tip. I also thought it was “Tiny” Kangaroo… .
Stan Freberg, “The Great Pretender” https://www.youtube.com/watch?v=zPnETiP8V9I
“Heartbreak Hotel” stan freberg heartbreak hotel - YouTube
“Banana Boat (Day-o)” - YouTube
and others too numerous to mention.
“Fish” and “Rats in my room”, sung by Leona Anderson, from her album “Music to Suffer By”. 365 Days #238 - Leona Anderson - Music To Suffer By (mp3s) - WFMU's Beware of the Blog . The other tracks are worth a listen.
A couple of ethnic novelty songs, “Snack for Santa” and “Michael’s Market”. Also there’s “The Czarnina Kid”, a Polish Dragnet parody, and “(A Visit from) Gwiazdor”, a Polish parody of “Twas the night before Christmas”. Budding Renaissance Man : Mad Man Michaels
Neither should the efforts of Leonard Nimoy:
This thread is extensive now, so forgive me if I missed this in my skimming:
Green Jelly - Three Little Pigs: Green Jelly - Three Little Pigs (Official Video) - YouTube
Who Put the Bop in the Bop She BopShe Bop by the Platters
Walk the Dinosaur by Was Not Was
Transfusion by Nervous Norvis
Hot Rod Lincoln by Commander Cody’
And of course my favorite
John Jacob Jingleheimerschmidt
which I can never find.
“Snoopy vs. the Red Baron” by the Royal Guardsmen
But then you’d have to explain who Snoopy is …
