An interesting short.
I thought the voices you used for the characters were creative, it helped me identify their personalities. I liked how the boy was speaking similarly to Olde English, it made me laugh. The random arm grasping the phone and the caller made me laugh as well, you have a good sense of humor.
The animation could use some work in a few places, mainly at the end and when the guy was dancing. I thought the plot could have been a bit more elaborate, just so we could get some background information on the character. Some tweaking here and there should help your skills majorly improve.
I thought the music was very good, I chuckled at the Super Mario Brothers 3 theme and how his ringtone was Axel F. Overall, it was an entertaining flash. Good stuff right there, keep up the good work.
