During Bill Belichick's first interaction with his now-girlfriend Jordon Hudson, he actually gave her an autograph -- one in which he thanked her for an impromptu lesson on logic.
Check out images of the signature that TMZ Sports obtained from one of Hudson's ex-Bridgewater State University classmates. You can see the former New England Patriots head coach wrote the then-21-year-old a sweet message on the inside of a textbook titled "Deductive Logic" -- expressing his gratitude to her for "a course" on the subject -- before he slapped his John Hancock on it.
