Quote from Amy Farrah Fowler in the episode Spoiler: We Couldn't Get Green Lantern
Amy Farrah Fowler: I made rugelach. Jay Garrick / The Flash: Thanks, honey. Amy Farrah Fowler: So, what's this all about? Jay Garrick / The Flash: They want me to use the Cosmic Treadmill to get back to their universe. Amy Farrah Fowler: Oh, great. Let them have it so I can park my car in the damn garage.
