Next time on The Amazing Race...
Zebras! Rachel and Mark seem to be by themselves while in a go-cart wildlife viewing type thing? Surrounded by Africa's wildlife, teams mark their territory. Rachel and Vanessa argue. OH SNAP. THIS IS NASTY.
Rachel: "What are you? 38?"
Vanessa: "Oh yeah. I'm 38... and I still look younger than you."
Then Vanessa tells Rachel she needs to get her nose done before her boobs.
