Season 1, Episode 14
The Nerdvana Annihilation
Penny: ... Second of all, the door to the stairwell of the other building was locked, so I had to go down the fire escape, which ends on the third floor, forcing me to crawl through the window of a lovely Armenian family, who insisted I stay for lunch.
Leonard: That doesn't sound too bad.
Penny: It was eight courses of lamb, and they tried to fix me up with their son.
Leonard: I'm sorry.

The Itchy Brain Simulation
Near the end of the episode
References to the very recently deceased Armenian video shop owner (Nerses Manoukian) who Leonard needs to find the family of to return a rented video game to in order to make Sheldon happy.
Leonard ends up saying he went to the Armenian Church and the funeral looking for relatives, but there weren't any. Sheldon suggests he go to either Armenia or Lebanon to find the family. Leonard doesn't want to go to Lebanon to find the family, buy Sheldon says he should, since he likes hummus.
