I'm going to cheat and post a video tonight. (In defense of such a decision, I had 3 hours of sleep last night, wasted my morning arguing with civil servants, and the video itself is quite funny).
The following is a humorous routine from a Colombian TV program entitled "Sabados Felices" ("Happy Saturdays"). The "teacher" is giving English language lessons for Colombian slang and colloquialisms.
Those who aren't familiar with some of these sayings (i.e. "Y la Ñapa?") will most likely have a difficult time understanding what he's saying. Yet those that understand American and Colombian cultures will surely chuckle heartily at the routine.
