Penny asks a favor of Leonard and Sheldon: to let the furniture delivery men into her apartment when they make the delivery of her recent purchase. She gives them a key to her apartment for this task. Leonard and Sheldon regret agreeing to do so when first the delivery men will not carry the delivery up the four flights of stairs, and second when they see the pigsty that is Penny's apartment, which just does not sit right with Sheldon's orderly attitude. Penny also ends up regretting asking them when Sheldon uses the key to sneak into her apartment at night when she is sleeping to tidy up, a task in which Leonard participates. Can Penny ever forgive them for violating her personal space, regardless of how immaculate the apartment looks? Written by

Howard mentions Sweden has no space program. At the time this was true, but since then they have developed a space program. See more
When bringing Penny's furniture up to her apartment, Leonard and Sheldon lay the box on the stairs and Leonard states "Now we've got an inclined plane. Force required to lift is reduced by the sine of the angle of the stairs..." This is incorrect, as the force required to lift it stays the same. The force required to push the box up the stairs is half of that required to lift it. See more
Men do things for women without expecting sex.
Those would be men who just had sex.
CHUCK LORRE PRODUCTIONS, #184 Don't fall for a woman who has had sex with one of your rock n'roll heroes. No matter how emotionally evolved you think you are, you will never enjoy listening to Eric Clapton again. Don't lurk around web sites where people comment about your work unless you're drunk. Don't use emoticons. You're too old to communicate like a twelve year old girl. Don't forget that you are the product of a culture that went stark raving mad about ten thousand years ago. Adjust your thinking accordingly. Don't answer TV critics question about the state of TV comedy. It's a trap. Don't eat anything bigger than your head. True in the sixties, true today. Don't believe that crap that you're as young as you feel. Your feelings lie. Don't hug men while shaking their hand. Enough already with that. The shake/hug (shug?) is probably something Roman guys did when their empire was in decline. See more
