Carl Wheezer is the asthmatic, food loving best friend from The Adventures of Jimmy Neutron Boy Genius, which aired on Nickelodeon in the early 2000s. His wheezy delivery became a favourite for short edits, and clips pairing his voice with croissants spread on video platforms and soundboards as a shorthand for over the top excitement. The joke relies on recognition of the character and the contrast between an ordinary pastry and his breathless reaction, which is why it still appears in meme compilations today.
