Networking in Psych

I've been rewatching Psych on Netflix as my way to relieve stress from the daily workday. It's been great and then yesterday I watched an episode that really hit some interest bones. The episode contained:

1. Kenan Thompson who was hilarious in All That
2. Jaleel White who made the whole of Family Matters
3. Acapella singing which I do enjoy and wish I could sing and be part of a quartet or something.
4. Computer Security and Networking references which I'll discuss.
5. American Ninja which hilariously, I didn't understand the name drop reference because I never knew the actor's name so I assumed he was the director.
