I think that’s a cheap insult.
Clint is liked by a great number of people for his performances and his personality.
It looked to me like a planned but mostly ad libbed performance. It was quite short and charming and full of personality.
Yes he is getting old, but making fun of that is not going to make points for anyone with others who have a greater sense of respect and decency.
Clint put down Obama & Biden like no one ever has.
