Shmendrik, oder Die komishe Chaseneh (Schmendrik or The Comical Wedding) is an 1877 comedy by Abraham Goldfaden, one of the earliest and most enduring pieces in Yiddish theater. The title role of Shmendrik was originally written for the young Sigmund Mogulesko, and derived from a character Mogulesko did when auditioning for Goldfaden earlier that year. The role was later famously played by actress Molly Picon.
The play is loosely based on an earlier Romanian language play, Vlăduţu Mamei (Mama's Boy), transferred to a setting in a family of Hasidic Jews, a milieu that was a standard butt of humor among the "enlightened" Jews of the Haskalah.
According to Jacob Adler, the play was such a sensation that a year after it was first performed in Bucharest, when Israel Rosenberg set about presenting it as the second play of his newly formed Yiddish theater troupe in Odessa, "Shmendrik" had already passed into the Yiddish language, both as a term of affection and derision, but also as slang for a sneeze, for money, and for the police. 
Shmendrik is an idiotic and clueless mama's boy, a hopelessly poor student at a religious school, whose mother is completely blind to his faults. The main plot is set in motion when his mother arranges a marriage for him; the girl in question is not only appropriately appalled by Shmendrik, but is already in love with someone else. The plot, of course, centers on how she will evade the inappropriate marriage and be reunited with her true love.
