Kiddie Gridiron: "Miss Nelson Has a Field Day," at the Circa '21 Dinner Playhouse through May 8

It's been more than 20 years since I read Harry Allard's series of "Miss Nelson" children's books, but it's hard to forget Viola Swamp, "the meanest substitute teacher in the whole world." Miss Nelson Has a Field Day, currently playing at the Circa '21 Dinner Playhouse, features Swamp (Liz J. Millea) as the no-nonsense alter-ego of Miss Nelson, the kindly math teacher at Horace B. Smedley Elementary School. The show is as funny as I remember the books being, and judging from the laughter that was constantly erupting from the audience of mostly elementary-school students at Friday's matinee performance, I wasn't the only one who thought so.
