Acts of playful stealing: 
Those that are accustomed to snatch [foods] from each other out of playfulness and good humor, resultant of the Purim spirit, are not considered to transgress the prohibition of stealing, and so is the custom. [This applies from the first night of Purim until after the Purim meal on the second night, for a total of two nights and one day. One may even say a blessing over such foods. Nevertheless it is best to refrain from such acts.]
Learning Miseches Shikorim or Miseches Purim:
It is forbidden to learn Miseches Shikorim or Miseches Purim even on Purim.

 Beir Heiytiv 6976/13; Dvar Shmuel 193; Ruach Chaim 696/8; Kaf Hachaim 696/61; The above Poskim write Miseches Shikorim however seemingly they refer to Miseches Purim.
