I had to call in a few favors. But if you don’t call in favors to look at women in bikinis and assign them numerical grades, what the hell do you call in favors for?

Our reading
An editorial interpretation.
The speaker justifies calling in favours by treating access to judging women in bikinis as their obvious purpose. The rhetorical question makes a narrow desire sound like a universal rule. Its humour comes from the confident defence of a goal that the wording itself exposes as shallow.
