Worst. Experience. Ever.

I cant think of my worst day, but I can think of my most embarrassing.

I had to stay back for t-ball training when I was younger and really had to use the toilets. I had a phobia of school toilets because they were horrible, so I went for a piss in the bush.
Just as I was starting, a whole bus load of kids drove past. I remember everyone's heads turning around, laughing and pointing.
