I saw this video the other day. I just couldn't help but post it here. I think the main reason why we laugh at it is because we know there is more truth to it than error. We have to laugh at it or else we become convicted at our selfish heart even during a time of worship. It made me think of this quote by A.W. Tozer:
"If you cannot worship the Lord in the midst of your responsibilities on Monday, it is not very likely that you were worshiping on Sunday! Actually, none of us has the ability to fool God. Therefore, if we are so engaged in our Saturday pursuits that we are far from His presence and far from a sense of worship on Saturday, we are not in very good shape to worship Him on Sunday" (Whatever Happened to Worship, 122).
