It's that chest emblem, I tells ya... who can resist that big "S"... sooo tempting...(It's been repeatedly established in comics that Batman wears a dark outfit with a bright yellow emblem specifically so that crooks WILL aim at it- the only part of him protected by bullet-proof armour. Makes sense... but won't crooks be even MORE tempted to shoot at Robin's multi-coloured outfit? Unless, of course, that's ALSO part of the plan... Man, Batman really isn't going to win "Father of the Year"...)
