פירוש על עבודה זרה 82:13

Shmuel’s statement, that fragments of idols are permitted, seems to contradict the second clause of the mishnah, which states that a fragment that contains a hand or foot is prohibited. These fragments should always be permitted according to Shmuel.
Shmuel answers by limiting the mishnah to a case where the hand or foot is on a base. If it is on a base, we can see that this is not really a fragment but a full idol. This mishnah always reminds me of the giant foot in the television series Lost. Never really understood what that was, but it made an impression.
