Who can fit in a plenum?

Today Mike and I were both busy so only he briefly stopped by the house tonight. His dad Bob, however, was busy at work on our furnace and water heater area. He managed to crawl into the plenum (where the air furnace pushes out air) in order to inspect it and clean it out. Anne took this picture which is apparently right after he was completely tucked up in it.

Tomorrow, Mike and I hope to get out there early. Mike will be on water heater duty while I will try to work of all/ some of the following:
- scab the holes in the drywall (entry way wall, purple room, master bedroom)
- put kitchen baseboards back
- continue moving boxes from garage to house
- assemble baby's new toy shelf
- meet "sprinkler whisperer" and get irrigation fixed
- meet new gardener and get the yard on the road to recovery
- rearrange living room and dining room with rugs this time
- add putty to baseboard nail holes
- put baby proof latches on the doors with long handles (as opposed to door knobs) the baby has figured out

Fingers crossed the water heater gets done before tomorrow night and we can actually live there by the weekend.
