Sometimes adding a little humour during a presentation can get the audiance's attention, and break some barrier. When a presentation gets interupted, that is the perfect time to do it. For example, if the interuption is two people fighting or arguing, you might say: " okay, that's just the side show, let's get on with the main one" or, "For your information, those two guys are part of this presentation. They are actors who have been paid to keep you awake, so lets carry on." If the interuption is a school bell, you might say: "okay, to your disappointment, that bell is to signal the end the class next door, and not the end of this presentation, let's continue. ..." . etc.
At the end of the presentation, it is actually okay to say "this is the end of our presentation", but you could wrap it up by thanking the audiance, and wishing them a safe journey home, or just crack another joke, to help them remember you, and your presentation.

One way to start a presentation is to state what the audiance can expect to hear, and perhaps what you would expect from them. Once again, many people start a presentation / speech with a joke, to create a more relaxed atmosphere and thus a more willing audiance..
