“Just got a job as senior director at Old MacDonald’s Farm. I’m the CIEIO”

The “EIEIO” in the song “Old MacDonald’s Farm” shouldn’t be confused with the position of “CEO,” but there are jokes. “@TheFagCasanova: Old Macdonald’s farm has grown into a multi-national dairy company, and he is the self-appointed CIEIO” was posted on Twitter on December 11, 2010. “Pleased to announce that I’m soon to be joining the board of Old McDonald’s farm as their new CIEIO” was posted on Twitter on April 21, 2017.

Wikipedia: Old MacDonald Had a Farm
“Old MacDonald Had a Farm” is a children’s song and nursery rhyme about a farmer named MacDonald (sometimes known as “McDonald” or “Macdonald”) and the various animals he keeps on his farm. Each verse of the song changes the name of the animal and its respective noise. In many versions, the song is cumulative, with the animal sounds from all the earlier verses added to each subsequent verse. For example, the verse uses a cow as an animal and “moo” as the animal’s sound. It has a Roud Folk Song Index number of 745.
