The guys are surprised to see a beautiful young woman in Sheldon's office. They are even more surprised when they learn that she is Sheldon's fraternal twin sister, Missy Cooper, who is in town only for two days to attend a friend's wedding. Against Sheldon's wishes, Leonard invites her to stay with them, which she accepts. Leonard, Howard and even Raj (who is participating in a pharmaceutical study, which includes testing a new drug to overcome extreme shyness) fawn over Missy. Using the argument of potential genius offspring, Leonard convinces Sheldon, who abhors physical and emotional contact even with family, that he needs to act brotherly in looking out for Missy's best interests when it comes to finding a suitable boyfriend. Who better in that role than his roommate. Ultimately, the guys come to a solution on who should pursue Missy. But what will Missy have to say about their choice? Written by

Sheldon says that a cuckoo bird is a superior creature that is placed in the nest of ordinary birds and then eats all the food leaving the other chicks to starve to death. The cuckoo chick, however, actually hatches first and pushes the other eggs out of the nest so that it receives all of the food. The cuckoo is also not superior to the "ordinary birds" by which it is raised. See more

If the wedding's not until tomorrow, why don't you stay with us tonight?
Oh, I don't think so. Shelly doesn't like company. Even as a little boy, he'd send his imaginary friends home at the end of the day.
They were not "friends". They were imaginary colleagues.
In the opening scroll of the time line when it gets to 91,000 there is a mistake the dates read 93,000BC 92,000BC 91,0009C 90,000BC for some reason 91,000 is a 9c not a BC. See more
