Absolutely, Joker is associated to laugh. Out of control, improper and strange laughing.
It was a nice talk with Connie about the character in the movie. The laugh of Joker, uncontrollable laugh, is a sign of his mental disorder, actually.
Wondering about his uncontrollable laugh, we just googled it. We found that suddenly and involuntary outburst of laughing and /or crying in an exaggerated manner or inappropriately is one of signs of Pseudobulbar Affect (PBA).
The episodes of PBA can last for several minutes and often occur many times in a day.
Uncontrollable laughing and/or crying often occur with unrelated to mood state or social context, so this episodes can be troublesome in everyday life.
