'Productive Day Off' should be an oxymoron.

...But I am having one. Here's another shirt design. Use with critical mass rides and the Coop. Gas stations, Hummers (the 4-wheeled kind), and frequent drivers are contraindicated as violent reactions may occur between those wearing this shirt and occupants of said objects. Side effects may include, but not limited to: One-finger salutes, Disputes over public right-of-way ownership, general road laws, and a generally smug feeling of 'doing the right thing'. You're welcome.
