8x10 "The One with Monica's Boots"

Monica buys very expensive boots and promises Chandler to wear them all the time. After a while they are killing Monica's feet but she doesn't dare to tell Chandler. Joey's youngest sister Dina (Marla Sokoloff) is pregnant and comes to Rachel for advice. Phoebe finds out that Sting's son is in Ben's class so she goes to see Sting's wife (real wife (Trudie Styler)) pretending to want to talk about Ben and Jack in order to get tickets to Sting's concert.
