I saw a video of a panel at Sakura Con 2013 where the people attending the panel would take part in a competition of sorts to guess what anime opening/ending would be playing. Below is the video of the panel. It looks like fun, however I myself do not have the materials to pull off a panel like this. Thought I could put a suggestion in the Panel Forum.
Link to video (FYI: the video is almost 2 hours long)
