How do I express "this made me laugh"?


This is the kind of simple question I'm often too embarrassed to ask, because
I should probably know this by now. But here goes...

I was ordering something at a cafe, and I noticed some slightly awkward
English on the menu something that made me laugh. It wasn't super funny or
anything, it just caught me a little off guard. The cashier noticed me laugh
and looked puzzled. So I pointed at the text and said:

> これを笑{わら}わせた。

This happens all the time where I speak off the cuff, and then after the
moment has passed, I realize I almost certainly said it wrong. Unfortunately,
unlike other cultures, in Japan people rarely call you out. The cashier didn't
look at me like "what the hell did you just say?", she just smiled. Leaving me
unsure if I basically spoke complete nonsense and she was being nice, or that
maybe I was close enough and she couldn't be bothered to offer any
adjustments.

Passive and causative verb forms and the right particles to go with them have
always been a source of trouble for me.

I think I should have said:

> 僕{ぼく}を笑{わら}わせた

I am the thing being made to laugh, so it's acting on me, so I take the
particle `を`. However, I want to make the thing I'm pointing at the focus of
my sentence, not me. So, maybe I should have said:

> これで笑{わら}わせた

In a sense, I was made to laugh _by_ this thing I'm pointing at. It's a
shortened form of:

> (僕{ぼく}に)これで笑{わら}わせた。

I often turn out to be totally wrong, so, am I wrong again? What would be the
best way for me to express, while pointing at the text on the menu, " _this_
made me laugh"?

Also see [this question and answer about the causative and passive forms of
笑](https://japanese.stackexchange.com/q/6864/119) for related information. A
joke is an interesting edge case, because, as explained in answers below, a
thing has no animacy, so it doesn't "make" people laugh, but a joke is the
result of actions between people, so in a sense, the joke us a proxy that can
be said to "make" people laugh.




笑わせた(笑わせる) is the causative form of 笑う(笑った), so  

> これを笑わせた。  
>

means "(I) made it laugh."  

> 僕を笑わせた。  
>

means "(Something) made me laugh", so logically speaking this statement would
be correct in your situation.  

> これで笑わせた。  
>

would mean "(I) made (someone) laugh with this." (I think the で works as an
instrumental/具格 case here)  

> (僕に)これで笑わせた。  
>

doesn't make much sense. Probably you meant to type:  

> (僕を)これで笑わせた。

? But this is more like "(Someone) made me laugh with this."  
"This made me laugh" literally translates to:  

> これが僕を笑わせた。

However, normally you don't say it this way in Japanese, because the Japanese
language tends to avoid using [無生物主語(inanimate
subject)](http://ja.wikipedia.org/wiki/%E7%84%A1%E7%94%9F%E7%89%A9%E4%B8%BB%E8%AA%9E%E6%A7%8B%E6%96%87)
(as user4092's post states), especially in verbal/casual communication. So I
think you should say it more like this:  

> (僕は)これで笑ったんですよ。/笑ってしまったんですよ。(I) laughed because of this.  
>  (僕は)これにorこれを笑ったんですよ。/笑ってしまったんですよ。(I) laughed at this.  
>  これが(ちょっと)おかしかったので、(僕は)笑ってしまいました。/笑ってしまったんですよ。 etc.

... using 僕 as the subject. (The 僕は is normally left out.)

To sound even more natural, you could just say like
「(いや、)(ちょっと)これがおかしかったんで・・・」「(あぁ、いやぁ、)この英語が(ちょっと)おかしかったんで・・・」etc., as @Haruo
says.
