Tacos... in a microwave? YOU BURNED TACOS IN A MICROWAVE!?!
Eh, well... I mean, that sounds sacrilegious (THEY'RE TACOS!!

Rest in Peace, tacos! -sniffle-) - but I can one-up you!
I was microwaving tea in sophomore year in college and I didn't put water in my mug.
Just a teabag. In a mug. In the microwave.
Our campus housing was evacuated because of that.

I still have the cup I did that with! It's one of my faves. For a solid year there was a singed scar in the inside of the cup but it eventually washed out over the years.
