Guys. Guys. I never noticed this until just now.
Peggy and Bucky have the exact same Social Security Number.
(Forgot where I originally got the image, but it was definitely Tumblr. Terribly sorry about that).
I actually thought that was weird the first time I saw it, but then I remembered that 987-65-4320 and 987-65-4329 (which you see with Howard and Jim) are SSNs used for advertisements and other fictional public images. They are like the 555-____ phone numbers in books, movies, and television.
