Neither he nor his wife appear in The Sims, although their son Jeff does. Les' name may be a play on "Less Pleasant". According to his SimDNA in SimPE, his hair was red before it turned grey. According to his age data, Les had 26 days left in the elderlife stage when he died. Like most pre-made deceased Sims from The Sims 2, he is completely unplayable without the use of hacks or third party programs, such as SimPE. Les' facial structure is almost, if not identical to the 14th Maxis face template in Create a Sim.
This Sim has no character data and cannot be resurrected in-game. For more information, read this guide.
