I don’t know if there’s any device that epitomizes the classic sitcom more than a surprise party. HasModern Family given us one before? If not, "Party Crasher" is more than enough, giving us the whole double-secret shebang, with Manny falling for the bluff and bringing home a girl to what he assumes is an empty house, then kissing her in front of a giant crowd of family and classmates. It’s all very pat and simple, which is fine, but the best part of this side of the plot is Jay and Gloria’s relishing of committing various minor crimes. It’s a fun moment for a couple that isn’t always allowed to have them, and I wish there was more of that here.
