My Daddy is Hilarious

Now Dad has got a mohawk -
It must be two feet tall!
It's scraping on the ceiling!
Oh, I don't like this at all.

Dad usually looks so cool, so it's a bit surprising when he starts appearing with outlandish new hairstyles...and eccentric clothes...diving flippers...Has he gone mad? The big relief (reveal) is no, it's a fancy dress party!
