Feed the Birds the Birdwoman Cries

I love Mary Poppins and one of my favorite songs is the one about the woman feeding the birds in the park.

I saw all this bread laying on the ground outside the West Wing. Had no idea where it came from. We haven't made rolls in months. Have we had an intruder? A Peeping Tom? Someone casing the place who brought their own lunch? What is going on?

 On closer  inspection I see that it is Expando Foam. Bill had used this to help in weatherproofing the siding. He sprayed it into voids, let it dry, and then cut it flush. Now there are little muffins all over the lawn.

I'll get these picked up before the birds see them and ingest what I am sure are toxic chemicals.
