No I don't feel insulted, nor do I find if funny. This is entertainment for the mass, by mass in this case I mean the uneducated.
To me it is just not right, I know it may be a prank, but there is a way to make people laugh other than use stereotypes.
Additionally, I did not say it was racist, as if you call someone else racist, your racist.
A educated person would have figured I was describing the events in the video as stereotypical.
Get your facts right.

Edit:
Last but not least:
"And these prank calls don't really hurt the person being pranked."
Misses my point in which the prank is hurtful to the race being targeted.
If it was your race and the mass took it seriously, it would be unfair, and supporters of the video are directly or indirectly at fault.
