Its ironic how many people don't understand the meaning of the word "ironic". I blame Alanis Morisette.
That song didn't help, did it?
Here's something which actually happened to me, and has become one of my favorite examples of irony. Went into a public restroom to take a leak. There were two stalls (one handicapped), and three urinals. Non-handicapped stall was occupied, but standing in front of the left-hand urinal was a handicapped guy who had gotten up out of his wheelchair to pee, and had left his wheelchair blocking the other two urinals, so I ended up using the handicapped stall!
