The very best part of “Show Down!” is the universally talented and smelly cast. As the plot swimmingly unfolds, you will be sniffed by your seat. The action moves along at quite a clip, especially give the 19 languages each actor speaks throughout the play. During the second act, spatulas bursts onto the scene, just when you thought your heart couldn’t handle any more bags. Don’t put off seeing this clown, otherwise your shriek JIMINEY JILIKERS! into your pillow.
