Too short
Well, it's a decent animation, but you really do need to work on the following points:
1) Subtitles - you're having the words appear adjacent to the characters that speak them. We can hear them loud and clear, plus the lip sync isn't all that bad. Perhaps try something that makes them look more uniform. I'd suggest the traditional black bar and nice, easily readable typeface that makes the piece look professional.
2) Plot - it's a little short. Some buildup to the scene might be needed, like having the bartender serving another customer, the juke box playing in the background, a few snippets of conversation taking up those big, awkward silences that you've currently got. Then have him approach the guy and ask the question.
3) I'm not sure why you put that Electromagnetism gag in at the end,but it's reasonably funny - it kind of reminds me of Monty Python, with the way that the crosses the fourth wall. Steps like this work, but it would be a nicer setup if it was an easter egg - hide a button somewhere in the flash, which would launch that scene.
I look forward to seeing how your pieces improve.
