We can make plurals easier. How about:
one sherrif two sherrifim
one stewardess two stewardi
a pair of scissors one sciss
one yoyo two yoyi
one berry berry-berry
On the way up Mt. Hood, there is a cut made through a leg of hillside for the hiway. This leaves a hugh hunk of rock on the right which has come to be called 'silent rock'. The story goes that while building the new hiway a worker lost his life. In honor of him everyone in the car stops talking and turns off the radio while passing through this cut known now as silent rock. Whether the story is true or not I don't know, but it has become a nice tradition.
Speaking of traditions- here's one I have learned from my wife: When we are on the road we often pass those signs which show a deer in mid-jump with its front legs up and bent. It therefore follows that just when we pass these signs we both quickly lift our hands up to our chests (wrists up, hands down) and then back down again. It's silly; it's stupid; but cute. Pass on the tradition! I'll bet all the girls are saying, "Hey, that's neat!" Al the guys here are saying, "Oh Gawd! Shut up Yarddog!"
