I'd LOVE to, but...
-- I've got a Friends of the Lowly Rutabaga meeting.
-- I promised to help a friend fold road maps.
-- I've been scheduled for a karma transplant.
-- I'm staying home to work on my cottage cheese sculpture.
-- It's my parakeet's bowling night.
-- I'm building a plant from a kit.
-- There's a disturbance in the Force.
-- I'm doing door-to-door collecting for static cling.
-- I'm teaching my ferret to yodel.
-- My crayons all melted together.
