You're thinking of Burdock, a much bigger plant. In the last picture I can see a plant with whorls of green leaves, which is Cleavers, Galium aparine. You can pull up lengths of it and throw it at your friends; later in the year it has tiny round sticky seeds. The leaves have tiny hooks on them which stick to anything in its path.
