Remember that California mom who thought it was an awesome idea to give laughing gas to her son and his friends while they ditched school? Well, now she's going to spend six months in jail.

Maria Antonia Mendez pleaded guilty in April to felony child endangerment and three counts of contributing to the delinquency of a child, fancy legal terms for letting your 13-year-old and his pals suck on giggle juice when they're supposed to be in algebra class. Mendez received the jail sentence earlier this week, at which time Judge Dennis McConaghy said he "can't fathom how somebody doesn't realize that's a bad thing to do." Amen, sir.

Actually, wait, there are four circumstances in which I can kinda, sorta fathom why Mendez might have thought this was a good idea, even though it's clearly not:

1. She believed she was the dentist from "Little Shop of Horrors."

2. She and the kids were watching an "According to Jim" marathon and decided nitrous oxide was the only way to make it tolerable.

3. She believed she was Dennis Hopper's character in "Blue Velvet."

4. After singing a round of "If you're happy and you know it, suck some gas," she couldn't resist sharing with everyone.
