My manager, while apparently trying to blast us over taking too much time to understand a product (that no one in the team knows about completely):

I don't understand why you guys don't understand the severity of it. How will you support the product if you don't even know it? There's no comments or anything also, just code! You guys should be able to grasp it!

I'm sorry, what now?

(The part about no comments is true, by the way)
