Just because something is awkward doesn't mean it's funny.
This especially applies to screenwriters (of, for example, The Office and Cop Out).
A conversation that is awkward is uncomfortable, which makes the audience wish it would end. Drawing this conversation out for a loooooong time is not funny, and it's not entertaining; it just tortures the audience. For example, every scene involving the dimwitted parents in the Transformers movies.
Awkward != Funny
Awkward <> Funny
Awkward ≠ Funny
