Poachers in the Hundred Acre Wood

Charlie Brown is the sole Peanuts character to unconditionally accept "Pig-Pen" for who he is, even defending "Pig-Pen's" uncleanliness in one strip...

Love, Wikipedia

I love that there is a whole character based on the classic stinky friend.

Who is your stinky friend?
