What was the last thing you made that was horrible?

Last week or so, I tried this recipe from "The Hip Chick's Guide to Macrobiotics." It was a baked casserole of seaweed, onions and butternut squash. That doesn't even SOUND good, I dunno what I was thinking. It was so gross! (And I normally like seaweed.)

What was the last thing you made that was a real "yuck!" ?
