Who wants to eat anything at Monica's (Courteney Cox) Thanksgiving dinner when everyone can watch the runaway Underdog balloon at the Macy's Parade? Elsewhere, Ross (David Schwimmer) and Susan (Jessica Hecht) try to bond with Ross' yet-to-be-born baby through the magic of reading. And Joey's (Matt LeBlanc) latest modeling job leads to embarrassing implications. With this episode, Jane Sibbett takes over from Anita Barone in the role of Ross' ex-wife, Carol. ~ Hal Erickson, Rovi
