Y-O-U-R means your!

Tonight one of my favorite episodes of Friends was on TBS, "The One with the Jellyfish."  The reason it is one of my favorite episodes is because, towards the end, Ross screams at Rachel, "Y-O-U-apostrophe-R-E means 'you are', Y-O-U-R means your!" I come across this mistake WAY too often and it always makes me want to yell that exact thing! 

The fight between Ross and Rachel starts at about 6:10 minutes, and my favorite part is at about 6:55 minutes.
