Pillow Fight Club

[San Francisco's flash mob pillow fight earlier this year]

As a throwback to the days when life was easy, Banditos Misteriosos, ("an organization composed of artists, musicians, improvers and just-plain-everyday-people-ready-for-fun," according to its website), is sponsoring a citywide pillow fight Saturday on the Boston Common at 1 p.m.

Here's Bandito's rules:

1. Bring a pillow. (A soft one is preferred.)
2. Only hit those who are holding pillows.
3. Arrive early and remain inconspicuous until 1 p.m., then rush in.
4. Spread the word and bring your friends, kids, etc.

All pillow-fighters are asked to meet at the Cathedral Church of St. Paul Episcopal, 138 Tremont St.

And Bandito's best tip? Costumes are encouraged.
