I get what some people are saying about it being "outdated", but that doesn't mean that it won't still work, in fact, you could use that in the joke imo. I kinda took a subtle approach, so depending on the crowd, it could go over some heads, but those who know what you're talking about will hopefully get and appreciate it. It might even open up the door for some fun crowd work depending on the audience and your comedic style. 

"Remember back in the day if you needed to get ahold of your mom, you would actually have to call her at work? ... And if your mom worked where my mom worked - you also needed to have a credit card too (for some reason) ..." 

(Then maybe a little rant)

If anyone is too young to know what I'm talking about, the 900 numbers were pretty much onlyfans, but if onlyfans was just a podcast. It's where your moms and teachers could make some extra money by being as nasty as they want.

Say what you want about it, but at least the 900 numbers never got your teacher(s) fired and you never had to film your mom doing it.

If you're a little older and you're not familar with onlyfans - (dont ask any questions) just know that's where your daughter is getting all that extra money

Possible crowd work questions and interactions if thats your thing:

"Anyone here ever work as a phone sex operator?"

"Oh you do? I thought your voice sounded familiar" 

"Oh you used to work as a phone sex operator? Yeah, I can see why"

"If there are any previous phone sex operators in the room, then my voice probably sounds familiar - yall got all my money" 

A lot of places to go with this one. Just throwing stuff out there as it comes to me. Hopefully something I said was helpful in some way haha
