Edyos3: 11
אַף הוּא אָמַר שְׁלֹשָׁה דְבָרִים לְהָקֵל: מְכַבְּדִין בֵּין הַמִּטּוֹת, וּמְנִיחִין אֶת הַמֻּגְמָר בְּיוֹם טוֹב, וְעוֹשִׂים גְּדִי מְקֻלָּס בְּלֵילֵי פְסָחִים. וַחֲכָמִים אוֹסְרִים.
He also ruled leniently in three cases: One may sweep between the couches [on the Sabbath and Yom Tov], one may put in-cense [on burning coals] on Yom Tov, and one may prepare (i.e., roast) a young goat with its entrails alongside it on Pesach nights. But the Sages prohibit [these three acts].
