I was out walking with my 4 year old daughter. She picked up something off the ground and started to put it in her mouth. I took the item away from her and I asked her not to do that.

"Because it's been laying outside, you don't know where it's been, it's dirty and probably has germs" I replied.

At this point, my daughter looked at me with total admiration and asked, "Wow! How do you know all this stuff?"

"Uh," I was thinking quickly, "All moms know this stuff. It's on the Mommy Test. You have to know it, or they don't let you be a Mommy." We walked along in silence for 2 or 3 minutes, but she was evidently pondering this new information.

"OH...I get it!" she beamed, "So if you don't pass the test you have to be the daddy."

"Exactly" I replied back with a big smile on my face and joy in my heart.

Lawn mower

In 1830, English mechanic Edwin Beard Budding (c.1796 - 1846), inventor of the lawn mover, signed a manufacturing agreement with John Ferrabee, Phoenix Iron Works, Stroud. Budding based his design on the helical cutting blades he had seen on cylinders run over newly woven cloth to cut the pile for a smooth finish. His patent (No. 5,990, 31 Aug 1830) described his mower to replace hand scythes for "cropping or shearing the vegetable surface of lawns, grass plats, and pleasure grounds." It had a cast iron frame with a large roller that turned a series of cogs which rotated the blades. Production was increased in 1832 by license to the agricultural manufacturer Ransomes. Budding also invented the adjustable spanner.«
