I'm still waiting for the first character to start the singing of the dog-cat song while taking a constitution break. 

Rarity, 
does humming only work or can you sing it?

"One fine day with a woof and a purr
A baby was born and it caused a little stir
No blue bunny
No 3-eyed frog
Just a feline canine little CatDog
CatDog
CatDog
Alone in the world was a little CatDog
Out on the road or back in town
All kind of critters put a CatDog down
Gotta try to rise it
Gotta try to get along
Gotta walk together
Gotta sing this song
CatDog
CatDog
Alone in the world was a little CatDog
CatDog
(CatDog)
CatDog
(CatDog)
Alone in the world was a little CatDog"
