At the beginning of this episode Lorelai and Rory notice how Luke's specials board now says Luke's Special Omelette and Rory, looking very distressed, says it has not been changed from 'Four Slice French Toast' since she was born. She's being utterly silly and facetious, of course. In 'Hammers and Veils' after their Friday Night Dinner in Luke's you can cleary see that the specials board says 'Meatloaf, Mac & Cheese, BBQ Burger.' Further, Lorelai and Rory did not move to Stars Hollow and meet Luke until Rory was around 8.
Correction: Actually, Lorelai moved to Stars Hollow when Rory was at most a year old. If you remember, Mia told Emily that when Lorelai appeared at the Independence Inn with a baby in her arms, she took her in and gave her a home. Also when Lorelai addressed the town at the Town Hall Meeting in 'Chicken or Beef', she said, "... you know me. I've been a part of this town for. . .well, look how big my daughter is - for that long." (There are many others but space is short) Although there are references that may be inconsistent with these statements, they are the goofs and inconsistencies that make Gilmore Girls interesting.
