Scott is fond of sentences like that, especially with puns thrown in. I have no idea how he's so good at coming up with them. They took me a moment to understand so I'll explain with an example from this page [0]:

“I’m not going to make a deathbed conversion,” Tom said diagnostically.

The sentence indicates that Tom is dying and not currently religious, and the word "diagnostically" sounds like a mixture between "die" and "agnostic". They aren't quite funny when explained but when you spend 3 minutes trying to figure one out before it slaps you in the face it's a very good time

More examples:

“I went rock-climbing with my girlfriend,” Tom updated.

“The defibrillator worked!” Tom said, repulsed.

“My karate instructor died,” Tom said, desensitized.
