Gonna have to be that guy that wants someone to explain the joke

 

I think it’s just a surreal parody of what you would normally see in a page like that.

 

I mean at least Batman and Simba knew their fathers.

 

It's funny cuz all their dads are dead.

 

I just like how the Harry Potter one just says "Have a Father's Day". No qualifiers on that at all. It's a very passive-aggressive card.

 

I suspect you realize this, but there's obviously more we can't see, for the same reason Simba, Batman, and Spiderman have no feet.

 

Hmm? To me it just looks like only Simba that might have more written below. For Harry btw it says "Dad, Have a Father's Day."

 

I mean, I fully expect there's more under the thing, simply because it's such an awful card otherwise. I just found it amusing on the surface.

 

I would imagine it says something like 'Have a father's day / full of magic'.

 

Obligatory Youtube link. Also a wee bit NSFW.

Impressively enough, it didn't even generate the largest groan of the segment.
