Robert who? You may not know the man, but you surely know of his invention: Robert C. Baker invented the chicken nugget (nicknamed the "Thomas Edison of poultry," he’s also a member of the American Poultry Hall of Fame. Sort of like the Baseball Hall of Fame, but for chicken).

From the song:

Robert C. Baker died on a Monday
We all know his work, although few knew his name
A Cornell professor who taught poultry science
Forever enshrined in the poultry Hall of Fame
84 years worth of food innovations:
Chicken dogs, turkey dogs and turkey ham
Beyond them all stands Baker’s greatest creation
For Baker begat chicken nuggets for man

O, Nugget Man
O, Nugget Man
Headin’ on down to that old Promised Land
Happy the meals all have been since the day
That the Nugget Man came our way
