"In the French comic series Asterix, the main character's Asterix sidekick is Obelix, a menhir smith and "delivery man". His handling of menhirs is easy thanks to his superhuman strength. Although menhirs are featured prominently in the series (Obelix is frequently seen carrying one on his back, occasionally hurling them; he even offers one as a gift), their purpose and significance is never taken into consideration. In the issue Obelix and Co., the Romans devise a scheme to introduce a menhir industry and market, although it is also made clear that menhirs actually don't serve any particular purpose, and Roman citizens are soon overwhelmed. (At one point, the Druid wizard Getafix admits to Asterix that even they, the Gauls, are not sure what menhirs are for.)"
