When she phones Emily's mum in England to tell her that Ross has brain problems and thats why he said Rachels name.
When she goes to a restaurant with Rachel and Rachels friend who she kissed in high school.. Phoebe says someone she knew called Regina Phalange got alcohol poisoning.
And she uses it when she says theres a problem with the left phalange in the plane and everyone gets off... LOL
How long ago does Rachel suggest Ross started his story about xmas trees when theyre in the coffee shop?
