(R. Shmuel bar Rav Yitzchak): (Our Mishnah exempts one who was Motzi less than a Shi'ur of food in a Kli, even for the Kli.) This is when [the food] needs the Kli, e.g. [soft] berries (if one takes them in his hand, he will crush them. If it does not need the Kli, he is liable even for the Kli (i.e. he is liable for the Kli even though he is exempt for the food).

(Mishnah): If one was Motzi a live person on a bed, he is exempt even for the bed.

[He is exempt for the person] because a live person carries himself (he makes himself lighter).

(Mishnah): If one was Motzi a [whole] Mes in a bed, he is liable.

All agree to this. (R. Shimon argues only in the Seifa, when he was Motzi k'Zayis of a Mes or Nevelah, or ka'Adashah of a Sheretz.)

Question: Was it not taught [above, 9:4] that also [something with] a bad smell, the Shi'ur is any amount, and R. Ila said that even R. Shimon agrees about this, and R. Shimon agrees about Isurei Hana'ah! (All should obligate here for any amount! We could have challenged also Rabanan, who require a k'Zayis in the Seifa. We asked a stronger question against R. Shimon, who exempts even for a k'Zayis.)

Answer (R. Yudan): [Our Mishnah] discusses a dead Nochri without a bad smell, and he took it out for his dog [to eat. It is Mutar b'Hana'ah. It is Melachah ha'Tzerichah l'Gufah, but one is liable only for enough to fill a dog's mouth. Rabanan hold that a k'Zayis is Metamei, and they obligate for Melachah she'Einah Tzerichah l'Gufah. We explained this like Bi'ur HA'GRA, YD 349:1, CHASAM SOFER 93b.)

(Beraisa): If one was Motzi a half-k'Zayis of a Mes or a half-k'Zayis of a Nevelah or less than k'Adashah of a Sheretz, he is liable, and R. Shimon exempts.

What is Rabanan's reason? The Tum'ah was already decreased. (The case is, less than a k'Zayis remains, so Hotza'ah of a half-k'Zayis is Metaher.)

What is R. Shimon's reason? It is like R. Yudan answered [above]. It discusses a dead Nochri without a bad smell, and he took it out for his dog.

(Mishnah): For cutting one's fingernails one on the other or with his teeth; tearing out [by hand] hair from his head, mustache, or beard; braiding hair; coloring eyes, or Pokeses (applying a mudpack), R. Eliezer obligates a Chatas;

Chachamim say, these are forbidden only mid'Rabanan.

If one detaches something that was growing in an Atzitz Nakuv (a flowerpot with a hole), he is liable. If it is not Nakuv (has no hole), he is exempt;

R. Shimon exempts in both cases.

(Gemara - R. Avahu citing R. Yosi bei R. Chanina): When do they argue? It is when he himself cut [his fingernails on each other or with his teeth]. If someone else cut them, they are repulsive (he cannot cut them nicely. Even R. Eliezer exempts.)

According to Chachamim - R. Acha said in the name of R. Nachum citing Rav that one is liable only if he cut them with a scissors.
