Adult Adam, Barry and others in “Unfinished Business”

[voiceover] And so we were forced to avoid being our usual selves. Meanwhile, Pops was watching TV as Barry forced himself to like the Grateful Dead.

[groans] Stupid Grateful Dead. I've been listening to a bass guitar solo for 20 minutes.

Pops

That's a lot of bass.

Everyone knows no song can be longer than 10 minutes unless it's The Sugar Hill Gang.

Pops

I know what'll make you feel better. What's Happening!!

And I told you... This kid Matt Bradley is trying to take my place as supreme and almighty leader of the JTP.

Pops

No, I'm saying What's Happening!!

I'm losing my posse! How are you not getting this?

Pops

I get it! I mean... What's Happening!!

I told you what's happening 10 times!

[voiceover] Much like my mom, who tended to swear, this is what Pops usually said.

Pops

[in the past] What's happening? What's happening? What's happening? What's happening? What's happening? What's happening?

Oh! What's Happening!! I love Rerun on these reruns This is a classic. Rerun tries to bootleg a show, and then the Doobie Brothers stop an entire concert when they see Rerun taping them.

Pops

Thanks for ruining it.

Wait a minute. He ruined the concert. That's it! I'll record the Dead concert and get caught.

Pops

I'm gonna really ask this time... What's happening?

I'll tell you what's happening. I'm gonna make sure the JTP never see a Dead show again.
