Hoping to reproduce the "secret" cookie recipe handed down to Phoebe (Lisa Kudrow) by Pheeb's grandmother, Monica (Courteney Cox) makes a somewhat disillusioning discovery. Elsewhere, Rachel (Jennifer Aniston) goes into full control freak mode while teaching Joey (Matt LeBlanc) how to sailboat. And an embarrassed Chandler (Matthew Perry) inadvertently performs a "lap dance" with future father-in-law Jack (Elliott Gould) -- while both men are naked in a steam room. ~ Rovi
