Spinach

One time I worked at a place where we had this huge, industrial-sized fan at the front door during the summer. For reasons unbeknownst to me, this lady Pat from a pub next door walks through our doors with a plate of spinach.

Peter goes, "Watch, the spinach is going to fly all over the place when she walks by that fan,"

And it did and Pat was shocked and Peter and I died laughing.
