Majstori, majstori (lit. 'Handymen, Handymen', translated as All That Jack's) is a 1980 Yugoslav comedy film directed by Goran Marković. It has since become a classic of Serbian cinema. It was digitally restored for its 40th anniversary in a joint effort by the Yugoslav Film Archive and Vip mobile.

The film is named after the first verse of the poem Handymen in the House by writer Aleksandar Sekulić, which is recited in one of the final scenes by a drunken teacher played by Aleksandar Berček.
