Big Bang Theory Quote
Howard: As long as we're talking about betraying our friends, how about the month Sheldon spent grinding up insects and mixing them into Leonard's food.
Sheldon: Well excuse me, that was not a betrayal. That was an experiment to determine at what concentration food start tasting "mothy".
Leonard: You put moths in my food?
Sheldon: For science.
Raj: I can't believe you kissed my sister with moth mouth.
