Also if players think of a lot of stupid ideas and then check if you're going to give away hints or something let them do anything they want and make sort of a rule everything you say will happen. That's a lot of fun too.
I have a lot of great memories of idiotic actions I did with my first character but I didn't do it as often after I was allowed to do anything. But it works well and you can get a real humourous adventure if you like that.
For example I had to go on a ship recently and instead of just walking in (which would have been ok too) we decided to open a chest and get on board with the cargo. Till we wanted to get out and noticed we were the chest at the bottom and had a lot of other chests on top of the one we were in
