Re: I simply remember the next one
"I only remember the next one" simply means that when you are in a play, it's only important to know what you're going to say next. Even though it doesn't work like this, it would be absolutely fine if, as soon as a line has finished coming out of your mouth, you just forget it. As long as you know what to say next, then you're OK. Of course, actors do actually learn all their lines, that's the only way they can perform a play right from the beginning! Darling Larry was being just a tad sarcastic, yet what he said is technically true!
