(Note: Sung to the tune of Snow White And The Seven Dwarves's "The Dwarfs' Washing Song")

Sung by Pinkie Pie

Poison joke is a type of flower that only grows in the Everfree Forest. Or at least, that's the only place in Equestria where there is any, as far as anypony is aware. Physical contact with the plant causes amusing, yet extremely inconvenient symptoms within hours. Symptoms vary from pony to pony, although bizarrely it is always a symptom that provides the greatest inconvenience.

For example, Pinkie Pie, a mare that finds it hard to stop talking, was rendered unable to speak after her tongue swelled up so much she could do little but blow raspberries to talk.

She described it later as the worst time of her life. It probably wasn't, but that's not what's important here.

Bed of Poison Joke
It's no fun at all
My tongue swelled right up
Hitting my mouth's wall
Couldn't yodel or whistle
Even do a cat-call
Just go "Thrp-ubbbl-bbul-bpl-plb-hptl
thrp-thpl-thrp-blpl?"

Rainbow Dash's wings
Got turned upside-down
And Rarity's locks
Were the talk of the town
(Just not in a good way)
And this party clown
Was like "Thrp-ubbbl-bbul-bpl-plb-hptl
thrp-thpl-thrp-blpl!"

Twilight Flopple
Appletini
Don't get me started on Flutterguy please
But spitting and rasping was the worst trick
It also doesn't sound hygienic...!

I think that I drooled
On the library floor
If Twilight saw that
She'd show me the door!
But I couldn't protest
Never happened before,
Sayin' "Thrp-ubbbl-bbul-bpl-plb-hptl
thrp-thpl-thrp-blpl...!"

But lucky for us
A spa bath was made
That used special herbs
The Joke starts to fade
Well thank goodness for that
I can talk all the day
Sayin' "Oh, my gosh! I never realized how horrible it is not to be able to talk. I mean, I love talking so much, and when I couldn't talk anymore, my tongue was all 'ehhhh'! It was the worst! Don't you agree, Fluttershy?"
