According to a tweet from @real_eikaiwa, the following sentence:
"I don't think I've ever met anyone that made me laugh so much!"
But this doesn't sound right to me. To me, 「私のこと笑わせてくれる人」sounds like "someone who lets me laugh about myself". My translation would be rather:
"I think there aren't that many people who let/make me laugh at myself this much!"
What do you guys think?
