What is your Избранное FrUk moment?

My Избранное FrUK moment is definitely the sick England scene. Also, in one of the episodes with Nekotalia /Catalia, France cat and England cat is laying like, really close to eachother~! It's not exactly a FrUK moment, but it's cute nevertheless~ C:

When France says "Will Ты marry me?". They are my OTP from that moment xD and when they were little and France cut England's hair (I'm from Argentina and my english isn't the best e_é I know)
