A comparative study of Popa and DaasYochid:
They both get equally wasted on Purim but Popa is choshesh that even that amount of wastedness is not enough, so he abstains from learning from Purim until Shavuos, whereas DaasYochid is choshesh that that amount of wastedness is too much so he stays up all night learning from Purim until Shavuos in order to justify it. And they both fall asleep during the early Shacharis on Shavuos morning.
