KAPOOT, Lid Productions, at Strawdog Theatre Company. They’re made up in whiteface, but these are not your usual Marcel Marceau wannabes. Flog and Plotz–the clowns comprising the cast of Kapoot–are grotesque creatures with death’s-head visages (allegedly based on the masked demons of Hopi and Zuni mythology) dressed in striped suits like prison uniforms and headgear sporting protean antennae. Human nature being universal, however, their chief activity is taking advantage of each other: communicating in wordless monosyllables, they squabble over food and compete for the attentions of a pretty girl (conscripted from the audience) but unite in humble obeisance to a likewise inarticulate God. Cleverly staged scenes include a World War I flying fantasy and an imaginative sequence in which the mischievous Plotz manipulates Flog’s dreams.
