Sheldon and Howard in “The Rhinitis Revelation”

Sheldon

[frustrated with everyone about his mother not doing what he wants, after they volunteer to take her to go around Hollywood] What do I say? I say you need to stop ruining my mom's visit, with your [Leonard's] sushi, your [Raj's] sadness, and your [Penny's] slutty shirts. Stop it! [leaves to go to his room]

Howard

[to Raj] He's talking about her shirt. Your shirt is fine!
