Off the Couch: Build your weekend with Jfest, barbecue and Legos

Massive Lego displays, complete with lights and moving mechanics like this "Joker's Funhouse" Gotham creation, will be part of BrickUniverse, a Lego fan convention taking place Saturday and Sunday, May 18-19, at the Chattanooga Convention Center. / Photo from BrickUniverse

LISA DENTON: Barry, you're a dad, so I'd be willing to bet you've cursed a Lego or two, probably in the middle of the night. But a convention taking place this weekend at the Chattanooga Convention Center will remind us why we should appreciate these little engineering marvels.

BARRY COURTER: Just out of curiosity, I googled to see if "Lego foot" is a real ailment, and while there are pictures of people stepping on the night terrors, it didn't make the list of 10 common foot problems. Would have bet it had.

My stepson and son were both huge Lego fans, and it is being passed on to the grandkids. What a great toy, though I have to admit I am neither artistic nor an engineer. All of my Lego builds involved stacking them until they were so tall they fell over.
