There are even bullshit questions, ones that give the appearance that one has an idea or an insight when in fact they end up convolution the path to a solution that eventually emerges naturally...
The best bullshit question is always to ask developers if they are sure their solution is foolproof. This has two nice side effects if you are looking to suck up to management. 1)It shows you are concerned about the project/product/company. 2) Should something go wrong even if it is the tiniest thing you like you had a point. You get all this while not taking the risk of doing the implementation. That is bullshit 101.
