Scott Beyette's lisping, daft and desperate William Barfee was the highlight of the 25th Annual Putnam County Spelling Bee, a sweet, silly musical about competitive kids. In this Boulder's Dinner Theatre production, Beyette (who's also been doing some excellent directing at BDT) pulled off the neat trick of being hyper-funny and completely over the top while still communicating all the teenaged angst and vulnerability of Barfee. That's Barfay, he kept exclaiming desperately.
