Is this a good way to finish a PhD current status conference?
A problem with that kind of ending is that the last slide tends to be shown the longest, because of the upcoming questions section, and it's somewhat distracting to ask with a funny picture behind. Something an instructor told me long time ago, for any slightly formal presentation, is to just show the first slide again (the title slide), so that you can answer questions with just the title of the talk behind you, avoiding distraction.
