Joe is wrapping up his personal kitchen remodel and is having fun picking the new décor. He and Allan wander to the backyard in a discussion about what makes a plant a weed.

Allan gets into the benefits of a seismic switches for your gas lines and flood sensors for your hot water heaters but they are all easy to accidently set off. The guys wrap up with a look at ancient Roman toilets, the good, the bad, and the ugly.
