The Power Plant Employee (Simpson and Delilah) is an aging friend of Homer's, who works in Sector 7G as an employee at the Springfield Nuclear Power Plant.

When Homer regrows his hair with Dimoxinil, Lenny and Carl notice that Homer looks different, so they think he lost weight or got a tan. The power plant employee knows what the difference is, and that it's a new tie.
