Oh.. I remembered the worst bit.
We had a Hawaiian theme day at work and someone made jelly cups with cocktail umbrellas in them.
He ate the jelly but left a bit behind. He stuck the umbrella in the jelly cup and left it on his desk for around 2 months.
It was all festy but he didn't care. He refused to throw it out. In the end our manager told him he had to ditch it.
