Get back to work!
The No Loafing sign can be found in Strong Bad's Computer Room. Strong Bad originally put up the sign in 1987 to increase productivity. An early "Loafing Not Permitted" version of the sign from the 1936 era can be seen with The Strong Bad in 50 emails. This sign reappeared in an easter egg in the flashback email. In the virus email, the "No Loafing" sign makes yet another cameo, falling off the wall and turning into HTML code.
