Trying new substances

I've always gone for sweet foodstuffs when sploshing myself. I really like stuff like custard, chocolate sauce, and absolutely love porridge! However, inspired by jo_yo's "I'm such a messy eater" thread, I've got two tins of baked beans waiting for me in the kitchen along with... a big tub of gravy. I've never sploshed with the stuff before, and I'm still not sure if I'm going to, but the idea of using something new is rather exciting. I've got an old white T-shirt ready that I think would look much better in brown.
Anyway, it got me wondering if any of you have ever tried a new substance they ended up regretting, or even being surprised you liked? I'm not sure what category this gravy's going to fall into.
