The douchiest thing(s) a VC has ever done to an enterpreneur

Curious if people have stories they are willing to share. I've worked in startups for 15 years and have founded 2 companies. Here's what I have seen:

- Backing out of a handshake deal at the last min

- Forcing founder to sell so they can realize gains because they are going to be raising a new fund.

- An investor telling his new portfolio co. he just invested in that it was ok to poach from us.
