Does a bear sh*t in the woods? Rhetorical affirmations in Japanese. Is there any?


I could not find anything on this website nor with a (quick I admit) search on
Google.

Does Japanese have any "yes phrase" (or more technically rhetorical
affirmation) used to answer questions whose answer is supposed to be an
obvious "yes"? Such as:

> Does a bear sh*t in the woods?
>
> Is the pope catholic?

In fact, these expressions are so common in English that you can often find
them twisted in comical ways:

> Is the Space Pope reptilian? (Futurama)
>
> Is the atomic weight of Cobalt 58.9? (Ghostbusters II)

Given that sarcasm is generally is not a typical trait of Japanese people,
maybe something like this doesn't exist. Or does it? Anything similar?

instantly came to my mind, but probably this was created intentionally so that
it would sound like a "typical American joke", and I don't think it's used
outside otaku communities. I could not think of a more traditional expression
similar to this. A classic set expression for "obviously true" is

(mainly used in written Japanese), but this does not sound sarcastic or
humorous at all.
