Quote from Amy Farrah Fowler in the episode Spoiler: We Couldn't Get Green Lantern
Jay Garrick / The Flash: All right. If I'm gonna do this, I'm gonna need to change. [Jay gets up and walks over to some recessed shelves. He grabs a light fitting on the wall and pushes it upwards. The shelves part to reveal a closet containing his The Flash costume] Jay Garrick / The Flash: Amy, where's my helmet? Amy Farrah Fowler: [o.s.] In the secret closet. Jay Garrick / The Flash: No, it's not. Amy Farrah Fowler: Are you even looking? Jay Garrick / The Flash: Yes, I'm looking. I see your rollerblades. What are your rollerblades doing in my secret closet? Amy Farrah Fowler: I don't know. What's your cosmic treadmill doing in the garage?
