Some of you may be to young to remember Boner, but for people my age, he was a very important part of our childhood.

Andrew Koenig, who played Mike Seaver's best friend on the TV show Growing Pains, has gone missing. Koenig was supposed to get on a flight from Vancouver back to the US on February 16th, but he missed it.

"He went up to [Vancouver] to visit friends who last saw him on the 14th," the actor's sister, Danielle Koenig, tells Zap2it. "Any information we can get on his whereabouts would be helpful."

Several celebrities have taken to Twitter to help in the search for the missing actor.
