The Simpsons: 10 More Moments More Important Than You Realised
9. The Olmec Head
In Season 2's Blood Feud, Bart saves Mr. Burns' life when it is discovered that the two share the same rare blood type.
To thank the boy and his family for keeping him alive, Burns sends them the generous gift of a... thank you card. There wasn't even a cheque inside.
This escalates to the point where the billionaire is about to fire Homer when he realises the error of his ways. To make up for a rubbish first present, he sends the Simpson family a very unique offering.
He bestows upon them a colossal Olmec head; a large carving of a human head in the style of the Olmec people of ancient Mesoamerica.
Whilst the family are initially baffled by the head, they eventually accept it when Bart decides he likes it. Although, to be fair, he was happy with the crowbar used to open the crate.
The head has seen appeared in the background of dozens of episodes of the show, most often in the family basement. Seeing it in newer episodes is a nice reminder of the show's humble beginnings, even if the head itself doesn't actually do anything.
