Childish lyrics

I'm so childish, a little bit wildish
With my rumdiddlyumdiddlyumdiddly, I'm so deep
Well I'm so garish, a little unfairish
The way I pick you up, and drop you in a heap
I'm so unfaithful, in fact I'm a plateful
I won't kiss her, but I'll stare her up all night
I'm a stormy little singer, an unstable little swinger
If you're coming, come prepared for a fight
Well I'm so childish, a little bit wildish
With my rumdiddlyumdiddlyumdiddly, I'm so deep
Well I'm so uncaring, do far too much swearing
And if you read through my behaviour, you'll find I'm a creep
I'll play a stormer, yet in the corner
I'll be grumpy on my own, like I don't care
I'm a stormy little singer, an unstable little swinger
With a big rip, in the arsehole of my flares
Well I'm so childish, a little bit wildish
With my rumdiddlyumdiddlyumdiddly, I'm so mad
I'm so truthful, a little bit bruteful
But in sooth I know not, why I am so sad
I try my bestest, well as far the restest
Well it's just stuff that comes out wrong, and gets misunderstood
I'm a dandy little dreamer, a doctored misdemeanour
A didactic destiny schemer, bare with me if you would
