Watch it at Supernova Tube (click)Stuart is dating Penny, Leonard gives him a glacial advice. Meanwhile, Howard realized a serious bug with his ISS toilet system. It re-shoots the material back to the room.
During the date with Stuart, Penny said "Leonard" instead of "Stuart". She really meant "Sheldon" but that's another story. ;-) Anyway, is a slip of the tongue such a big deal or a definite proof of love? I don't think so. Also, ISS calls Houston with an FYI message: the whole crew had to go for a space walk.
