WHERE'S MY BRAIN?

Has anyone seen my brain I've left it somewhere 
Searched all around the house and it is not there 
Looked in the garden and even under the chair 
Misplacing one's brain is just totally unfair 

My brain was last used doing a puzzle I think 
Or was it used for making some kind of drink 
Should you happen to see it the colour is pink
Please put it in the post and send it to my shrink

I will keep on looking until my brain is found 
Try not to be too noisy and won't make a sound
It's not under my bed or lying on the ground 
Let's hope I find it soon and it hasn't drowned
