Well, given the amount of cleavage 'Peggy' has on display, we'd wager a guess Ed might be a fan of Modern Family co-star Sofia Vergara's embodiment of his wife from a previous life on Married With Children. 

Vergara, sporting a Peggy Bundy wig, captioned the below: "Do you like this look Ed, Oneal???" followed by many, many laughing emojis. He'd probably like it more if she managed to spell his surname correctly, she's only been working with him for how many years now?

Surnames aside, I think I speak for everyone when saying, "Wowsers." And "Modern Family writers need to write in a dream sequence involving this wig, immediately."
