Missing: One Brain

Has anybody seen my brain?
I lost it during math
It was so confused it ran away
leaving havoc in its path

I wonder where it is right now
Its probably having fun
Swimming in some ocean blue
or bathing in the sun

I hate it when it flies away
it leaves me feeling blue
Because then when I need to think
I don't know what to do

If you find it then please contact me 
I'm feeling quite distressed
Because I have science next
and I know we'll have a test
