If you don't know this, the FIRST pun you should have thought of is in this sentence.

Go easy on the puns, though--you are presenting to school officials. If they see a bunch of students making bad puns all over the place, they're not likely to look with favor on you. If one or two are used as an opener, that's standard practice to break the ice. If the school officials see a group of students that can make a reasonably professional presentation, they're more likely to support you.
