The presence of the minions itself. When it is known that:

• people roll their eyes at memes involving them, especially here.
• they generally add nothing to the meme
• used by boomers a lot on Facebook

For me, here’s what I was thinking when I saw this meme:

• wholesome-ish meme
• minions? Ew. What was the choice behind using them?
• the community is Lemmy shitpost?
• oh LMFAO it’s a nod at Facebook memes.
• funny.

Humor is subjective, and it’s ok if you don’t find a joke funny ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯
