Aren’t most memes “ha he said/showed the thing I know about!” anyway?

It’s like the big bang theory jokes. Mentioning something that someone knows can be enough for people to enjoy themselves.

69 has added sex appeal because of its meaning. Its the “thats what she said” type of thing. “Haha, you said the sex thing”

420 has added naughty appeal because drugs.

Basically its an “ooh you said the thing, and that thing is naughty!”

It’s fine, but not my cup of tea either.
