Sally says, "This kid at school said I have a funny face . . ."<BR><BR> Sally continues, "Is it all right if I tell him you're going to slug him? You can be my knight in shining armor . . ."<BR><BR> Linus replies, "I'd rather you didn't." Sally shouts, "What kind of knight are you?"<BR><BR> Linus replies, "I'm a dove knight."<BR><BR>
“Dove knight” sounds like a cleric/soldier mix for an RPG.
