One I have heard recently was from RnRC during the preshow film. While I was standing there a girl next to me yelled out, "Hey that's the guy from American Idol!" 
Another was outside of the Land Pavilion. A guest asked the CM where the Shrek ride was located. The CM told the guest that it was at Universal Studios. The guest said, "I know that." and then proceded to ask again how to get there from the Land Pavilion so the CM told them, "Go down across the bridge and when you get to the fountain to take a left. They they will exit the park thru the turnstiles, go to their car, get in, and drive toward the exit of the parking lot. After they exited the parking lot, follow the signs toward I4 and go east. Once on I4, look for the Universal Studios exit. Then pay to park in their garage, get out of your car, and walk toward the Studios. Buy a park ticket, if they didnt have one, and then go thru the entrance. Once there, head straight down the street and about halfway down it will be on their right." The guest then says, "So where is the Shrek ride?" I could not stop laughing!
Oh and heres another video for you.
