Joe Biden talking about 'a magazine with a hundred clips in it' and protecting geese

Joe Biden struggled during this speech, saying things like “I believe in the second amendment but nobody says you can have a rounds — a magazine with a hundred clips in it...” - he corrected that one, but later said “We protect geese more than we protect, no joke you can only have 3 shotgun shells when you go shooting for geese” - and I don't know what else or how bad it got after that.
