Synopsis by Hal Erickson
In Philadelphia for daughter April's math contest, Luke (Scott Patterson) visits Jess (Milo Ventimiglia) at the latter's new bookstore. Rory (Alexis Bledel) also shows up at Jess' establishment after a fight with Logan (Matt Czuchry), whereupon she and Luke exchange a few pointed words. Meanwhile, Lorelai (Lauren Graham) shudders at the thought of her parents (Edward Herrmann, Kelly Bishop) moving to Stars Hollow. The episode's title refers to the fact that Lorelai has named her pet dog Paul Anka -- which of course necessitates a cameo appearance by the "real" Paul Anka in a dream sequence.
