The grease zerk is named for....Oscar U. Zerk! So it's a good thing he invented them. Held at least 299 other patents and lived well as a result of his inventiveness.
And that's something I'm thankful for. To live in a time when good ideas are rewarded and widely used, that's a wonder we take for granted. It wasn't always that way.
