A father-son duo dressed as elderly women attempted to rob a convenience store in Leeds, England. 17-year-old Declan Pick wheeled his 38-year-old father Martin into the store in a wheelchair. Both were disguised in wigs and overcoats, clutching handbags.

From HuffPo:

Seconds after entering, Grandma Martin jumped up from the wheelchair, whipping out a shotgun that had concealed in his lap, under a blanket. The store owner chased them out, and the entire fiasco was caught on tape.

A Leeds County Court sentenced Martin Pick on Wednesday to 18 years in prison. Martin’s brother Mark, who manned the getaway car, was also sentenced to 16 years.

I think I just got a great idea for a Season 8 challenge…
