Amanda Seyfried's dog can't act, but he can balance things on his furry head.

Giving his A-list mom a run for her money in the talent department, Finn, an Australian shepherd, joined Seyfried on "The Late Show With David Letterman" earlier this week, where he demonstrated a pretty nifty trick.

"He balances things on his head," revealed Seyfried.

"No he doesn't," responded an incredulous Letterman.

"Yeah, he sure does," Seyfried shot back, eventually proving it by having Finn come out and then placing a hamburger (aka dog crack) on his head.

Seyfried was on the show to promote her upcoming movie "Lovelace," a biopic about "Deep Throat" porn star Linda Lovelace. The indie hits theaters August 9.
