Sir Laughs A Lot 

(n.)
That one kid you know that you can't be serious with or you can be the biggest comedian hanging out with him because he just laughs at anything/anyone/anywhere/ every time.

Me: "Yeah I'm going through some tough times, my parents are getting divorced."
Sir Laughs A Lot: "Hahahahahahahaahahahahahahaahahah!"

Me: "Knock-Knock"
Sir Laughs A Lot: "Hahahahahahahahahahahahahaahahahah!"

A lot of laughs

Something or someone who is fun and will probably make you laugh and have a good time.

Family Guy reference: Lois: Are you making friends in there, Brian? Brian: Yep, he's a lot of laughs.
