When you're trying to tell a funny story but you can't because you keep laughing.

You know that time when you're trying to tell someone a hilarious story but you can't explain it properly because it's so funny and you're laughing whilst telling the story?

Yep.

I'm extremely guilty of doing that. Like the other day, I was trying to tell my friend about when the Mad Hatter stole my Alice in Wonderland stickers in the mall (refer to previous journal post... or not) and I kept laughing and laughing while telling the story and she looked at me like I was a mental psychopath.

And after I'd finished telling my story she looked at me seriously and said, "that wasn't funny".
