Tearaway Richie Kinders faces two weeks of organising, taking part and watching flash mobs after being convicted of anti-social behaviour.
The 16 year old had been caught shoplifting, drinking and generally getting a bit carried away with it all.
Magistrates warned the young hoodlum to change his ways or face harsher penalties.
The sentence will see the rowdy delinquent choreograph a surprise birthday flash mob in a Nandos for 42 year old homosexual Alan Phillips, and take part in a surprise interpretative dance for Cats Eyes, the charity for Blind Cats.
WH Smith spokesperson John Menzies said:
"We're glad Richie's been caught. He's been a right menace to us. He once bought a Sunday Times but hid the Observer Food Monthly magazine in the folds of the paper. You can't do that. You can't have the magazine without buying a newspaper.
"We are already in talks just now with several youth amateur drama groups to try and organise flash mobs in our branches so that we can see him involved."
Humanitarian groups are appealing the sentence:
A spokesperson for Liberty said:
"We believe Mr Kinders should have had a custodial sentence. The idea of forcing someone to take part in not one, not two, not three, not four, not five, not six, not seven, not eight but loads of flash mobs is horrendous. It's torture and effectively corporal punishment. Every time someone is around a flash dance untold damage is done to their body as their insides curl up on themselves. Two weeks of this is two weeks too many. In fact it's three weeks too many."
