It's not from lifting the playfield, because if it was, I'd be made of lead by now.

I took the lead scanner from work and scanned a bunch of stuff in my house.

The vinyl window blinds, and the vinyl windows themselves were off the chart lead.

Or if you ever had a wood deck, wood play structure, or a treated wood fence in the yard, the soil below it is an toxic wast dump of arsenic, copper, lead, chromium......the worst of the worst.

I think he's referring to the lead paint on the pencils.

I don't think wood pencils ever had actual lead in them.
