Could I Get Just One BWHA-ha-ha? Please?

What is with the people who must end every emailed, texted, or posted sentence with LOL? Or even intermittently pepper LOL throughout the sentence? It's like some very bad laugh track in written form, and the people who use it typically aren't very funny.

Given the choice, I would choose Tourette Syndrome any day. The language has greater diversity and is certainly more colorful.
