Winry often chucks her wrench at him when he comes to visit with broken limbs, due to her worry about his dangerous situations.
Winry: *sees broken arm* *has a fit and chucks her spanner at Ed*
Winry: Have you broken your arm AGAIN???
Ed: Well, when I get my original limbs back, I won't ever need automail(prosthetic limbs) again...
Winry: How can you prefer real limbs to the beauty of automail???
Ed: Automail geek.
Winry: Alchemy geek.
Person2: That, that is an Edwin(:
