About halfway through this episode Spike, who is living with Xander, ruins his clothes when he trys to wash them and is given a hideous shirt and shorts of Xander's to wear until he can get more. When the remaining members of the Scooby Gang head to the school to help Buffy it can be seen that Spike is still wearing the shorts. However, when they arrive at the school and Spike pretends to be an old friend of Xander's (with a rather unconvincing accent) he is wearing blue jeans - where'd he get them and when did he have time to change on the walk over?
