I went to a Citrix conference the other day.
When I left, I got a pair of Matrix-style sunglasses (get it? Citrix / Matrix).
When I got home, and tried them on, just to see, if they could make me look like Neo (they couldn’t – and I didn’t look like Trinity either), I noticed this warning, attached to the sun(?)glasses:

Sunglass warning
