The Queen of Hearts - S7.E2

Sam has just baked a piecrust and needs 2-dozen (4 and 20) blackbirds that sing to finish the pie (a la ""Sing a Song of Sixpence), which gets everyone on the subject of nursery rhyme food. But unexpectedly, The Queen of Hearts shows up in the store in search for the tarts she baked and the Knave who stole them. While the others are helping the 'demanding' queen for the tarts, Jeff found them and the queen thinks Jeff was the thief. Jodie was able to convince her that it could not have been good old Jeff and manages to make friends with the queen. When they finally catch the knave, he admits that he was going to give the tarts to, get this, Old Mother Hubbard.
