He's 93 & confined to a wheelchair.  If a bad joke makes his day, he can grab my @ss anytime.  Even though he's an ex-pres, I wouldn't expect his life to be all that entertaining right now.

Even 5 years ago at 87, he was no Harvey Weinstein.  Be kind to the old guy and just let it go.  It's not like he's going to jump out of that chair and rape you.
