Accidentally Awesome

For once, he’d listened to his wife,How to ameliorate her life,And he went without delay,To take her on a holiday.
But as he hastened to comply,In proving he was one sweet guy,He left his glistening lab in lessThan pristine order, I confess.
While those two hurried who knows where,One petri dish abandoned there,A part of his criteria,Was moistened with bacteria.
When they returned, that fateful dish,Was not as clean as they could wish.Bacteria, possession had,And things were looking rather bad.
Except one place had not been ‘got’,No icky growth upon that spot.Instead, a little bit of moldHad landed there and taken hold.
Beating off the icky stuff,And proving it had strength enough,Its presence brought discovery,And new ways for recovery.
I guess you’ve guessed by now that guyWas christened Fleming from on high.And penicillin, started smallS’the best discovery of all!
After that, we note that heMade no startling discoveries.His wife, by his chaos dismayed,Decided she would hire a maid.
