The Sore Losers just got their new line of hats in, and Eddie thought their dad hat's had a flaw in them. But it turns out, they're actually just "in fashion." The flap in the back that allows for adjusting the size of the hat is apparently supposed to stay out rather than be tucked in. That's at least according to Raymundo, who told Eddie that all the college kids wear their dad hat's like that now. Raymundo's been wearing dad hats like that for awhile now, and he told Eddie that if he wants to be cool he has to wear his hat that way too.
Eddie admitted he does want to be good with his fashion so that his kids think he's cool.
