It has been recorded by many, not Manny, Manny didn't that I know of.

"Life Gets Tee-Jus Don't It" is a country music song/spoken word recital that was written and sung/spoken by Carson Robison (backing by The Pleasant Valley Boys) and released on the M-G-M label (catalog no. 10224-A). In August 1948, it reached No. 3 on the Billboard folk best seller and juke box charts.[1] It was also ranked as the No. 7 record on Billboard's 1948 year-end folk record sellers chart.
