Looking for something to do tonight? You can head to The Hague for the ABC (American Book Center) Treehut's Open Mike Night, held from 8-10pm. About once a month (on the 2nd Friday of each month), the ABC Treehut encourages performers of all types to come out and show off their talent. All are welcome, from poets to comedians to short story writers.

They even provide a clear list of Open Mike Night Rules:

1) Performers: please be present at 8 pm at the ABC Treehut to confirm your slot
2) No entry fee (or free drinks) for performers
3) Your first performance of the evening should be 10 minutes long, or less
4) If there is still time, you might be able to perform again
5) Performances can be in any language
6) You may offer your work (book, cd, etc) for sale to the audience

As stated, entrance is free for performers, but if you prefer just to watch, there's a EUR 3 entrance fee. The ABC Treehut is located at Lange Poten 23 in The Hague.
