Somebody told me : Oily hands + Slippery Bowl

The scope
Friend X told me that there was an incident during a steamboat with his friend. As his friend was holding a bowl of soup, due to his oily hands and a tighten grip, the bowl of soup went vertical and landed with the contents on his friend's shirt.

Verdict
Oily hands + Slippy Bowl = Where is the nearest hang ten?

I wish i was a witness, free laughter.
