The YesDear 5000, or Boyfriend Helmet, is a helmet Lizzie used to get Nigie to spend time with her in Operation: L.I.Z.Z.I.E., instead of the KND. In Operation: S.N.O.W.I.N.G., Jimmy Nixon McGarfield obtained and modified one so that it would work on girls and make Lizzie his "bride". The YesDear 5000 works by controlling the mind of the man wearing it, making them unquestionably obedient to the woman controlling it, though not without severe pain. The helmet is controlled via remote control, and the severeity of its effects can be increased or decreased accordingly. If the helmet is on the head of a mind-controlled person too long, it fuses to the victim, leaving them brainwashed forever.
While powerful, the helmet can be disabled if the person wearing it is stressed to the point of creating enough feedback to destroy it, although this is very uncommon.
