EXCELLENT!
Now, this is how a flash should be made: long, hilarious, and in minimal memory amounts! The Intern picked up power with each and every joke, eventually making me laugh constantly, and wouldn't END. I expected something shorter with that file size.
Being so talented, you're the first guy I'll ask from this site to collaborate with my brother. He's been diddling with Flash for months and hasn't acquired a consistent, disciplined work ethic (sad, he's a great artist). I won't press anything on you, but I would ask you if you're available, and you ought to take that as a compliment. You're among the elite already.
The techniques used to compress so much in under 1.5 MB would be appreciated if displayed in a summary on the Newgrounds' Bulletin Board System, to be perused by those trying to conceive big epics in little packages. Also noteworthy is sound, which might not be fully clear, but it sings through well-handled voice-overs.
Submit more Flash soon, and know that you're now in demand!
