Here are some options:
* Gelōtodrama: Combining gelōtos (laughter) and drama (play). This would literally mean "laughter-play" or "comedy."
* Kōmōdrama: Combining kōmos (revelry, merrymaking) and drama (play). This suggests a play filled with humor and revelry.
* Eukhairesidrama: Combining eukhairesis (pleasantness, grace) and drama (play). This implies a play that is lighthearted and charming.
Ultimately, the best word would depend on the specific type of "funny play" you're describing.
