Question: Isn't the plot inherently flawed? Chow was already in Las Vegas, so there's no real correlation between him and the main characters, so he would've stolen Marshall's gold, whether or not he met them right?
In the scene where Alan flirts with the store clerk, they share a lollipop. You can hear a "crunch" indicating that she chewed the lollipop. In the next shot, she takes the lollipop out of her mouth and it is still completely intact.
