I'm watching TV show 'Shark Tank'. One person asked, "How did you earn your money?" then competitor answered
YMCA. Shoveling mud. Everything you can think of.
Does this mean he actually shoveled the mud literally? Did he shoveled the mud at YMCA? Is that a job that you can get paid? like industrial work? or does it mean idiomatically he did hard things? I tried to find 'shoveling mud' in google but nothing really came out.
I found the video of it for context. https://youtu.be/S9eTGdfKQV8 it started around 1:45.
