I'm familiar with Mfuge but not the videos you are referring to. One of the funniest videos I've seen in a long time was done at Healing Place church in Baton Rouge during a conference this past April. It was filmed throughout the conference and shown during the final session. A young lady made her way around the lobby, coffee shop, and bookstore during the break times with a hidden camera following her. She did some crazy things to people that she got away with because of the atmosphere. People at church tolerate a lot of strange things that they wouldn't tolerate say, in a mall or somewhere else. She would walk up to complete strangers and take their sunshades out of their pocket, put them on and walk off. She took people's coffee from them, tasted it, then handed it back. She walked up to people's conversations and stood between them like she didn't have a clue what she was doing. It's hard to describe but the video was hilarious. I wish I could get a copy. My son who is 15 would be the perfect candidate for such a video and we have talked about doing it. It's something you have to be very careful with though. You never know how people will react.
