I know it's fun, but please don't do this. Pun threads are malignant growths. They're easy to reply to, since each individual pun doesn't take a lot of thought. Most upvotes are given out sparingly, for interesting or insightful comments, but everyone involved in a pun thread votes up the rest of the comments in the thread. This leads to a self-perpetuating cancer with no real meaning or value to anyone but its contributors.
