I have a few regular dice pairs for craps, I have a Yahtzee set of 5, some extras tucked inside their board games... but one thing is for sure... The dice I own are all 6 sided.

37 probably is too many

more than 1,.. hundred is too many.
can't have too many di
Imagine if you lost them in a fire,
I wouldn't want to lose my di in a fire.

I don't have any

Think i got a pair of dice in a boardgame somewhere at home
Most likely covered in dust

Have you ever rolled a nat20?

Yes ofc.

So answer the topic question.

Always keep 2 dice on you in case a random street craps game starts up.
Same with a hacky sack

Let me know when you find out
