When I think of laughter, 
I think about silly kittens. 
When I think of laughter, 
I think of silly goats. 

Why are they so silly? 
It makes me laugh. Ha-ha ha. 
Why are they so silly? 
I think they're telling jokes! 

Sometimes when I laugh I think 
my face gets this funny shape. 
Sometimes when I laugh I think 
my nose-- my nostrils, they just inflate. 
Ha-ha ha-ha ha! 
[Look at my nostrils flare!] 

Sometimes when I laugh I think 
my hair, it grows an inch. 
I think it does happen and when I laugh it's gone 
but, that does not make any sense! 
Ha ha ha ha ha! 

Sometimes when I laugh, I think of 
lots of laughing billy goats. 
Sometimes when I laugh, I think of
trolls being thrown over bridges. (What?) 
Ha-ha ha-ha ha! (What?) 
[You know, the Billy Goat Gruff and the trolls and the bridges?
I think after they threw goat over, they laughed about it.] 

Sometimes when I laugh, I think of 
fish swimming in little ponds. 
But, I don't know why they'd be laughing 
except that we're really funny to look upon. 
Ha-ha ha-ha ha! 
[Silly humans.] 

Sometimes when I laugh, I think of 
lots of silly kitty cats. 
Sometimes when I laugh, I think of 
monkeys dancing and going splat. 
Ha-ha ha-ha ha! (What?) 
[Splat, you know, because they're dancing and they
fall down. Makes you laugh, too.] 

Sometimes when I laugh, 
I think of a silly joke. Like, 
why did the elephant eat that pancake, 
did it know it would choke? 
[What? That's not funny at all. 
The elephant, I hope it feels better. 
You shouldn't laugh when people get hurt.] 

Sometimes when I laugh, I think of really funny jokes. Like, 
why'd the chicken cross the road, 
if chickens aren't that old? 
(What? Hahaha!)
[Well, because the, you know, the eggs came before the chickens,
because first they were reptiles, right?] 
(Yeah.)
[But it made you laugh, so--] Hahahaha ha! 

[Oh...]
[I don't know that this song is that funny.]
