Without further ado, your best bets (be warned—there are lots of clowns, costumed characters and other trademarked mascots):

Country Market — Alexandria Country Day School will host its 20th annual Big Top Country Market on Saturday on the soccer fields next to the school from 10 a.m. to 3 p.m. Carnival games and rides will be provided along with airbrush tattoos, arts and crafts, a cakewalk, clowns and balloon animals. There will also be a marketplace with vendors and food from Famous Dave's BBQ. It's just up the ridge. Check it out. Admission is free.

Family Fall Festival — Armistead L. Boothe Park is the site for Alexandria's Family Fall Festival. The event will be held rain or shine from 10 a.m. to 3 p.m. (moving indoors to Samuel W. Tucker School in the event of inclement weather). There will be plenty of entertainment, including appearances by the Beale Street Puppet Theatre and musician Dan Mazer. Exhibits from the Alexandria Fire Department and the Ford Nature Center will also be there. And, yes, there will be face painting, pumpkin painting, hayrides, pony rides, scarecrow building and a visit from Robbie the Recycling Squirrel. Some attractions cost money.

Paula Poundstone — The standup comic is visiting the Birchmere on Saturday night. Her routine was pretty good in the mid-90s if you liked a lot of jokes about cats. Today, she's a frequent guest on NPR's always awesome "Wait, Wait… Don't Tell Me!" To purchase tickets ($39.50), click here.

Trade Show — The United States Patent and Trademark Office is holding its National Trademark Expo on Friday (10 a.m. to 6 p.m.) and Saturday (10 a.m. to 4 p.m.) near the King Street Metrorail station at 600 Dulany Street. On hand will be exhibitors, trademark characters, themed displays and seminars for kids and adults all illustrating the vital role trademarks play in the world's economy. It's free, educational and the Pillsbury Doughboy might just be there.
