Laughing Through the Grunts  Yes, it's 2010 but somehow America
is experiencing a caveman invasion. It's not enough that they
discovered fire and invented the wheel. Now the hairy apes have
come back to take over movies like 10,000 BC and Jack Black's
Year One, not to mention the Geico commercials. Now, if my
boyfriend cuts his finger and I offer a Band-Aid or has a raging
headache and I offer to give him medicine, he replies, "Cavemen
don't need (fill in the blank)." No matter that they were lucky
to live past 30. But one group of comedians who also doesn't
need Band-Aids feels a kinship to the Neanderthals. Defending
the Caveman, which opened on Broadway in 1995, is a parody of
the constant misunderstandings between men and women. Its
mission? To help their modern descendants understand one
another, minus all the grunting and hand signals. To witness the
peacemaking in progress, head to Arlington Improv for Defending
the Caveman at 8 and 10 p.m. Friday and Saturday and at 7:30
p.m. Sunday. Tickets are $25,
