Flaunting around…

I’m as astute as a flute
I’m as aware as a flare
I’m as obnoxious as a goat
Just to keep the world afloat!

I’m as bored as a bat
I’m filled with tat like your cat
And for a fact, I like rats
For their ticks, and their tacks

I’m as numb as a nun
I’m your chum, we have fun
I’m tweedle-dee
And you’re tweedle-dumb
