An Unusual Poetry-holder

My grandfather, of whom I have written about before, sent his entire family the following email this evening: I went in the hospital at 7 AM and it's now 11:30.... Dr. Valentine did the procedure, so I put a folded red heart where he entered*. lt said:

Come on in, I'm all cleaned up So please wear gloves and don't corrupt Examine carefully all 24 feet And nip all polyps from my fat seat. You may never again see this place So enjoy your stay, then retire my case.

The nurses and doctors said they liked the poetry.

*"Where he entered" refers to where the sun don't shine, if you get my drift... and the funny thing is, this isn't his first time putting poetry there under the same circumstances...
