My goto is to ask LLMs how many states have R in their name. They always fail. GPT 5 included Indiana, Illinois, and Texas in its list. It then asked me if I wanted an alphabetical highlighted map. Sure, why not.

What I hate about this is that, for GPT-6, they're going to do

if "blueberry" in prompt:
print("there are two Bs in blueberry")

and claim it is now more intelligent than GPT-5.

Great! I'll send you an email. Thank you, Kevin!

Got it. Thank you. I'll take Kevin up on it then!

Thank you, Kevin! I appreciate it. I'll let you know :)

Thank you very much for the kind offer! I'd be grateful if you read mine (I'm looking for a range of positions including R2 and teaching). Please let me know if and how I should proceed. Thank you!

Regression and other stories, chapter 16, has a discussion in the same vein that I really like (and some criticism of traditional power analysis): users.aalto.fi/~ave/ROS.pdf

The R package naming convention, especially when R is the only capital letter and you have to press shift only for that letter.
