Aaugghh! You won last time! I hate it when you win! Aarrggh! Mff! Gnnk! I hate this game! I hate the whole world!! Aghhh! What a stupid game! You must have cheated! You must have used some sneaky, underhanded mind-meld to make me lose! I hate you! I didn’t want to play this idiotic game in the first place! I know you’d cheat! I knew you’d win! Oh! Ooh! Aarg!
