A great toupological moment from Star Trek's third season episode "The Cloud Minders". These kinds of first-hand experiments are quite rare, and so the scientists at the William Shatner School of Toupological Studies and in particular those with the "Department of External Inter-Toupular Activity" are highly excited by the potential for knowledge that this clip could yield.
Does the mask clip the toup (which, at the front, crept round the sides a little in order to have a stronger hold) or Bill Shatner's real hair? Was Bill Shatner angered by this non-approved toupular interaction? There are all sorts of questions that must be answered!
