#1995: MC Hammer Age

XKCD comic, described below.
Transcript

[Cueball and White Hat are walking together.]

Cueball: Want to feel old? MC Hammer just turned 40.

White Hat: Wow.

White Hat: I mean, I guess that's not too surprising, right?

White Hat: It's been a long time.

[Caption below the panel:]
