Episode complete credited cast:
Penny (as Kaley Cuoco)


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 Huggo

Crazy Credits

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 »

The One With The Messy Apartment...
29 July 2015 | by (Australia) – See all my reviews

I love this episode. It's a great follow-up to the Series Premiere, and is just so funny. It's great because we learn more about the characters, about their histories, and quirks, which I love seeing.

In this episode, Penny asks Leonard and Sheldon a favor, to let the furniture delivery man into her apartment, whilst she's at work. Sheldon reluctantly agrees, whilst Leonard is happy that he's even being noticed. When the delivery man comes, he has no way of getting the box up the stairs, and since the elevator is broken, he just leaves it in the capable hands of Sheldon and Leonard. They try to get it up the stairs, and it doesn't go very smoothly. When they take the box into Penny's apartment, Sheldon discovers that she is a slob, and that night he can't sleep because of it, so he goes into her apartment in the middle of the night, and cleans. When Penny wakes up, she is furious, understandably.

Fun Fact: Howard is allergic to peanuts.

Fun Fact: Sheldon has a Master's Degree, and two PhD's.

Fun Fact: Sheldon is allergic to bees.

Fun Fact: The title refers to the cereals that Sheldon has on the top of his fridge, which are sorted by fiber content.

Fun Fact: We see the inside of Penny's apartment for the first time.

Best part of the episode: When Sheldon cleans Penny's apartment.

Overall, I give this episode a 10 out of 10, which in my ratings book is: Freaking Ridonkulous.
