If you compare him to the rebooted, Darker and Edgier Joker, the tv version would probably come across as pathetic. However, the whole show was silly, rather than scary; the Joker was the most threatening of a pretty much harmless lot of villains and he was still more comic than "dangerous". But personally, I don't find the evil of the darker Jokers "laughable" at all.

Before I leave for the night I felt I should point out that I didn't think that the Killing Joke picture would have fit - just that it was the best available image of the Joker in a "laughing" context I could find.
I think the best direction to go with this trope is to show a villain laughing or telling a joke (which may be reaching dangerously far into telling vs. showing).
Your beauty is radiant.Not anything I got. Took that (From Batman Beyond Return Of The Joker) coz I liked the menacing black shape, red eyes, contrasted with the silly "Bang!" gun.
Also, since you can't see the Joker all that well, no risk of confusing it with Monster Clown.
Found a better quality version of the image, and it's exactly 330 pixel wide

The colors a clearer too so you better see his outline

All look like Monster Clown, Try to go with him doing something silly or funny...
Hm, sorry I was misunderstanding the trope. Okay, the Batman Beyond pic is good.
Fight smart, not fair.I read this thread, and then while doing something completely other I saw this

We could also go for the STAS version of Toyman, though he may fall under the category of Laughably Terrifying.

Laughably Evil
Just A Face. And a rather weak depiction of the Joker, at that. There are dozens and dozens of better pictures of the Joker out there.
Unfortunately, there are surprisingly few pictures of the Joker laughing on Google. The best one is already used on The Killing Joke.
Of course, we don't have to use the Joker for this page. Could be another villain.
Any suggestions?
Your beauty is radiant.
