As far as passive aggressive notes go-- this one is pretty crazy.
Somewhere in the U.K., someone left a note on a stranger's poorly parked car that reads, "Nice parking [smiley face] Please don't reproduce. Regards, humanity."
The note also includes a condom.
On a survey on Mirror.co.uk, the majority of people responded 'I want to buy whoever wrote the note a drink," while just under 20 percent said "We should settle our differences like adults."
