Words like “thou,” “hic,” and “alderliefest” can make reading Shakespeare a real challenge. But the Improvised Shakespeare Company plumbs the language for laughs, using Elizabethan-style phrases and the Bard’s themes to compose its ad-libbed performances. Following an audience suggestion for a title, the company spontaneously creates a new Shakespeare play. Will it end in a wedding or a bloodbath? Since the cast members don’t know, there’s no way to tell before the curtain falls. Recognizing the bawdiness of the Bard’s language, in addition to the creative wordplay, makes these improvisers a hilarious fusion of high- and low-brow.
