Read, in this case.

Any kind of generalization won't work here, since it will be (for me) ear-grating American English anyway. Furthermore, since I'm Finnish I'm used to TV being in a foreign language and subbed (only shows for small children are dubbed here), so that's more the default state than anything else.

>but you generally find things more funny when you hear them rather then read

...and this is just personal preference. In addition to all this, I like the way subs bridge different cultures and teach languages.
