Task: Question Answering
Input (English): HOMO ERECTUS, a comedy set in prehistoric times, follows the exploits of the hapless Ishbo (Adam Rifkin), a philosophical caveman who yearns for more out of life than sticks, stones, and raw meat. Determined to single-handedly, advance the human race, Ishbo continually irritates his fellow Neanderthals with ridiculous inventions like the toothbrush, the spoon, and pants. The rest of his tribe, including his exasperated parents (David Carradine and Talia Shire), write off his absurd gizmos and forward thinking ideas as the ravings of an idiot, something that doesn't help his efforts to impress the beautiful Fardart (Ali Larter), the cavegirl he loves from afar. Fardart only has eyes for Ishbo's studly but dimwitted brother, Thudnik (Hayes MacArthur). As if things couldn't get any worse, the enemy tribe on the other side of the hill is readying for war. Will Ishbo ever win Fardart's love? Can he possibly survive a man-eating wooly mammoth or a man-hating tribe of beautiful but deadly Amazons? Can he finally pull his species out of the primordial doldrums before he's history?, Question: What is the name of Ishobo's dimwitted brother?
Output (English): Answer: Thudnik
