Odd compliments

Things people have actually told me that could be taken the wrong way
  1. "You smile like the joker!"
    "But like in a good way!"
  2. "You know so many useless things!"
    "But it's helpful!"
  3. "Your skin is my favorite"
    Kinda serial killer-y sounding
  4. "You have appealing shoulders"
    My friend said this one and then leaned on them
  5. "Your hands are like warm soggy waffles!"
    "But they're nice!"
