Actually, there have been a lot of people criticising the flowers on the other associated thread, along with the whinging I referred to. The only reason that the image you've posted is "a bit weird", as you put it is due to the text accompanying it. The flowers in that could easily be given to the knight from an admirer once the pesky dragon was vanquished.
I'd be way more impressed with the alternate suggestions if they hadn't been made without the benefit of hindsight and the general feeling of "I know better". Though I get the distinct feeling that any gift that BB made would have been wrong to some. Too many posters (not just on this thread, btw) simply complain. And it's the same few, generally. Prettying up a whinge with old links, nice images or some other fancyness doesn't make it any less of a whinge.
I don't understand why people feel a need to incessantly accuse and moan- it's not constructive. Those who genuinely have issues they want to raise end up getting their point hi-jacked by the complainers and self-agrandisers.
I would be willing to bet the entirety of my star menu that every single one of the complainants still managed to overlook just how offended they were and accept the flowers in the mail.
