That's an awkward situation to be in and I don't blame you for being bothered.
How did he react when he broke them? Embarrassed? Did he laugh? Does he have a thick skin?
I ask because depending on that you could play off it. For example, if he thought it as hilarious, you could buy a sturdy chair and jokingly call it "The Bob Chair" and tell him it's just for him? Kind of corny but oh well.
