When Leslie Winkle shows up she asks Leonard if he would want to fill in on the physics department string quartet. Leonard agrees to fill-in seeing as he plays the cello and to have the practice at his apartment. Penny asks whether there is anything going on between Leslie and Leonard. Leonard denies it, but Sheldon speaks as he always does letting Penny know “He asked her out once, it was an embarrassing failure”. Penny makes the remark they would make a cute couple.

After the rest of the Orchestra leaves for the night, Leonard and Leslie continue practicing alone, during such Leslie lets it be known she’s sexually available. After a brief conversation about Penny and “musical foreplay” Leonard and Leslie rush to his room.
