Actor Tim Robbins is having problems locating his ACADEMY AWARD - because his teen son JACK hid it four months ago.

In February (04), Robbins picked up the Best Supporting Actor OSCAR for his efforts in Clint Eastwood's Mystic River, which also spawned Sean Penn's Best Actor win.

But while Robbins remains proud of his win, he can't show it off because his and partner Susan Sarandon's offspring decided to play an extended practical joke.

Robbins says, "Honestly, I don't know where it is. My son has hidden it. My 14-year-old son has hidden my Oscar because I got him really good on April Fool's Day (01APR04).

"I got him with a really good one and he was so (infuriated). It's his April Fool's joke."
