"Ticklish Reuben" is a folk song written by Cal Stewart in 1900. Released on the Victor Label, the song is a prime example of the "laughing song" genre. Initially, the tune starts off normally, then descends into an abyss of maniacal, sinister laughing.
Oh,
My name is Ticklish Reuben
 From way down in old Vermont
 And ev'rything seems ticklish to me
I've been tickled by a feather
 I've been tickled by a wasp
 I've been tickled by a yellow bumblebee
I have always got a tickled sort of way about my clothes
 It doesn't really matter where I be
 I am tickled in the morning and I'm tickled in the night
 Something's always sure to tickle me
hah hah hah hah hah hah hah hah hah hah hah hah hah hah
 hah hah hah hah hah hah hah hah hah hah
(repeat x12)
Once I put some pepper into Dad's snuffbox
 And the way he acted was a sight to see
 Well he coughed and he sneezed till I thought he'd have a fit
 And then he took me out to tickle me
I was always getting tickled by someone about the house
 So why they take to ticklin' I could never see
 And the apple-butter paddle it is all in splinters now
 Daddy wore it out a-ticklin' me
