Episode Title:
Blood Feud.
Episode Description:
After Mr. Burns falls ill and desperately needs a blood transfusion, Homer discovers Bart has Burns's rare blood type. Homer urges his son to donate some, promising that they will be handsomely rewarded. However having received the blood, all Burns does is send the family a card. Enraged, Homer writes an insulting reply, but Marge convinces him at the last minute not to send it, but Bart unknowingly mails it anyway. Mr. Burns becomes furious and demands that Homer be beaten. Smithers calls off the beating, however, on the grounds that this action is no way to thank the man who saved Mr. Burns's life. He convinces Burns to instead buy the family a present.[44]
