Punky Brewster S02 E13 Christmas Shoplifting

Misled by schoolmate Richmond Matzie (Peter Billingsley), Punky shoplifts a cashmere scarf for Henry as a Christmas gift, and unknowingly switches bags with Mike, resulting in an innocent Mike being put in jail. Punky and Henry get Mike out when Punky explains everything. Henry grounds Punky for a month, with no TV for 2 weeks, and her punishment is to have a job during a Christmas sale at the mall.
