Things I have learned today:

Pyrex baking dishes sometimes explode.

Nothing like greeting my parents at the door with "Er, there's been a change in dinner plans. Mom, have you ever had a dish explode in the oven?"

Partially-cooked roast beef sitting in a profusion of glass shards is eerily reminiscent of a former house mate's "art" projects.

We vacuumed the interior of the oven.

My life? Very, very weird.
