some strange things have happened to me whilst using a microwave also... i once put a boiled egg in there to warm it up (the top was already off) and fuck me it went EVERYWHERE!
another time i was removing a bowl of 'Princes tender chunks of steak in a rich onion gravy' from there and as i moved it it litterally just 'popped' like some one had put a firework in the middle of it! i was covered in boiling gravy and lumps of steak
