The olfactory nerves are responsible for our sense of smell.

I saw a flock of olive-backed orioles flying overhead.

There are many old-schools in this town.

The old sods gathered for their annual reunion.

I found some old sticks in the backyard.

The old college tries were not enough to win the game.

The old squaws flew gracefully over the lake.

I saw some beautiful old man's beards in the garden.

I bumped into my old mates at the grocery store.

I tried thousand-year-old eggs for the first time and they were delicious.
