AVA: Oh, he’s adorable. And he [Luke] looks strong, is he strong?
LORELAI: Oh I don’t know. I don’t think he’s gonna be in a sideshow anytime soon, but he can get the lid off a pickle jar.
The Strongman, a man performing amazing feats of strength, was a circus sideshow attraction in the 19th and early 20th centuries. Yep, another circus reference! These days, Strongman events have become athletic competitions.
Ava’s later comment about hoping Luke is unattached is a sign that she is a single mother, like Lorelai. It seems as if Lorelai might have more in common with some of the Chilton moms than she thought. However, Ava’s interest in Luke has doomed her chances of becoming Lorelai’s friend, which is a shame as they seemed like they could have got on well together, and been allies in the Chilton world. Romantic and sexual attraction pretty much ruins everything in Gilmore Girls.
