I chock it up to being chalk full of bad grammar

Here's a pet peeve that I have: When people say that something is "chalk full" of something else. That's wrong. It's chock full.

I also get angry when people "chock one up." Wrong again. It's chalk, this time. As in, you're tallying a score on a chalkboard. Chalk it up.

This has come up all too often in the past few weeks.
