My grandpa (Dad's dad) had Parkinsons. One of the drugs they gave him was Ropinirole. It caused a severe lack of impulse control. He was wheelchair bound, so other than words, he was harmless.

He once told my wife "give me titties," when my grandma said "what did it say?" He said "give me kisses."

Another time, we were at my parents house. Both of my grandmothers were there. My mom's mom was also wheelchair bound and fat af. He told her that he was going to take her out back, bend her over the table and fuck the shit out of her.

These are only two of many instances.
