It may have been the fact it was 2 a.m. but that was the funniest possible thing that could have happened. Especially given the context that he swore for the first time in 6,000 years with a relatively tame "oh, bugger" and then took maybe five minutes to escalate to a full-blown FUCK (with italics!) and, like, I don't think Aziraphale gets enough credit for how Well, That Escalated Quickly he is about pretty much everything?? If Crowley was an angel that sauntered vaguely downwards, Aziraphale was one that took a running leap from "I should tell Cro-- er, Heaven that I've located the Antichrist!" to "fine, I'll find someone to murder a child for me handle this myself!" as soon as he figured out that Heaven didn't actually want to stop the apocalypse, it wanted to win it.

I love Mightily Oats! I have a rather complicated personal relationship with faith/organized religion so I was sympathetic to his inner conflict, and I really liked how that conflict was resolved.
