Today was Y Combinator Demo Day. While Paul Graham-approved crème de la crème were inside, pitching their racing hearts out, Peter Sullivan was outside, slapping fake tickets that proclaimed, "You have illegally been subjected to make a big investment decision based on a two-minute demo pitch" on the cars outside.

Mr. Sullivan is the CEO of the social travel startup Tripl, conveniently available for download via a QR code on the ticket.

We can only hope for Mr. Sullivan's sake that Silicon Valley investors pay more attention to pesky parking tickets than many a wealthy driver.
