Holy shit that must suck...good luck cleaning it.

On the plus side your wording is top notch.

That sounds terrible, but I laughed pretty hard at the term "fruit cheese." I wish you luck getting it cleaned up. You definitely don't want that smell sticking around.

It must have been left there a long time to get that bad.

Bright side: you could be the next Gallagher. His exploding watermelons don't have anything on your trick! I feel bad, that's going to be awful to clean. And from your description of the grossness, you will probably never eat watermelon again.

I'm in awe with your description... that's disgusting.

Very good use of adjectives for visual stimulation.

You do realize that because of the watermelon escapade most of the audience has now left.

Keep all possible windows/sources of ventilation open for as long as possible for a good while. It's probably the only way the smell will eventually dissipate.

try getting a high pressure hose and spraying it out
