Do you know of a poem that contains these features?

[RabbitLover]

I need a poem with no more than five verses and it has to include alliteration (e.g. big brown bears bubble) and it also has to have assonance (e.g. jub jub).

Thanks in advance.
And I mean a well-known poem, not one made up on the spot, but thanks anyway I guess!

i went to see big brownny bears bubble but bears bubble ended up in the jub jub. I tried my best!
