Gomer's middle initial is "S", according to his Navy Pay Slip.
In "Payday" Pyle Returned $10, thinking that was a weeks pay. However, according to Dept of Defense a recruit (E-1) earned $83.20 a month. To properly figure a weekly pay - you would take the monthly pay - multiple by 3 (Months) and divide by 13 (weeks) and the weekly pay would be $19.20.
Six is Gomer's lucky number.
The $10.00 Private Gomer Pyle (Jim Nabors) returns to the paymaster would be the equivalent of about $87.50 in the year 2021. The actual weeks pay for a private in the United States Marine Corps in 1964 of $19.20 would be the equivalent of about $168.00 in the year 2021.
