Episode complete credited cast:


A blue jay perched on his apartment window ledge is too much for ornithophobic Sheldon to handle. As no one - even the authorities (gasp) - seems to want to help him shoo away the bird, a scared Sheldon does whatever he can to get rid of the bird in any way he can. He turns to his two biologist friends, Amy and Bernadette, who try to help him get him over his fear. Their attempts have unexpected results. Meanwhile, Penny asks Leonard if he wants to go see a movie with her. He realizes that Penny's invitation is not a date, despite he deep down wanting it to be. But once he gets over the notion that this event is not a date, Leonard is able to relax and enjoy his time out, even more than when they were actually dating. As Leonard makes it abundantly clear to Penny that it not being a date has its own consequences, Penny decides to take her own actions to prove to Leonard that it is indeed not a date.

Did You Know?


The bottle of beer beside Leonard, that the viewer assumes that Leonard is drinking in the bar, is a real British alcoholic beverage actually called Newcastle Brown Ale. It is a brown ale, originally produced in Newcastle upon Tyne, in England, but is now (in 2016) brewed by owners Heineken in various countries. The version of the recipe for the USA was changed for certain health issues. Newcastle Brown Ale is perceived in the UK as a working-man's beer, with a long association with heavy industry, the traditional economic staple of the North East of England. In export markets, it is seen as a trendy, premium import and is predominantly drunk by the young, as portrayed in "The Big Bang Theory". See more »


Sheldon refers to the bird as a blue jay, however, it is a black-throated magpie-jay. See more »


Penny: I want to know what you told her.

Laura: Laura.
Leonard Hofstadter: Laura.
Penny: Oh. Okay, I see. So while he was telling you things, did he mention he owns not one, but two Star Trek uniforms?
Laura: Really?
Penny: Yeah. Wears them. Not just for Halloween.
Leonard Hofstadter: Hey, pal. You didn't see me telling Kevin that you thought cold wars were only fought in winter.
Penny: Okay. Then I'll return the favor, and I won't tell...

CHUCK LORRE PRODUCTIONS, #366 [Image of a cluttered desk containing a Mac SE, a glass of bourbon, dirty ashtrays, pencils, erasers, etc.] This photograph was my vanity card when I was working on Grace Under Fire and Cybill. I remember deciding on its composition by asking myself what were some of my favorite things. The answer, as you can see in the picture, was tobacco, bourbon and an old Mac computer. Eighteen years later, I still love my Mac. The other two items, despite my eternal affection, have been replaced with a bronchial inhaler and a metal folding chair in a church basement. See more »

very clever, good episode
20 June 2013 | by (Brooklyn NY) – See all my reviews

This is one of their better episodes. Besides being funny very often and showcasing Parson's (Sheldon) great acting abilities, I found the episode to be be very CLEVER about the tired old topic of nerdy, low self-esteem Leonard groveling for sex from pretty powerful Penny, but NO! Usually you NOT ONLY SEE this (Leonard's groveling), but you have to HEAR them all discussing all aspects of coitus -- wanting it, pursuing it, getting over it, etc, etc. Here, though, it was very cleverly well done. Since former lovers Leonard and Penny said they were on a friendship date, not the usual sex-romantic date, Leonard (and then Penny too) changed the usual routine and conversation -- like speaking his own mind, demanding his own choice of movie, hooking up with another girl while on the date. So, to repeat, I usually wince when I see Leonard and Penny speak openly and cloyingly about their love life, here it was rather fresh, different. Good job.

The second half of the episode was also nicely done -- about Sheldon trying to shoo a bluebird away from his apartment. The Leonard-Penny half was mostly clever with some comedy thrown in. The Sheldon-blue bird half was mostly Sheldon outraged at this comedy best.
