Analysis of HUH? what was that?

a buzzingly buzzutiful bee buzzed by my ear
 as i opened, popperty pop, my can of cold beer
 it ziggitly and it zaggity zagged in front of i
 then crashitly crunch it collided with a blowy fly
 their flipperty flapperty wings tried to flutter
 to stop them fallin''n' fallin' into the butter
 i was going to have some lovey toasty woasty
 but the buggly buggy bugs had spoilt it for me
 they're now wrestling in my d-d-d-dairy spread
 i hope that they don't end up dead dead dead!
