When the spec says can you do that again i say why i did it right the first time, i learned this from a guy named james at magic masters sincerely, Kyle

When a person ask, "Do that again!!"

i reply, " Once is magic, twice is entertainment."

works and gets a laugh ever time.

-peace

I like those both, you could also say
"Do that again"
"First time is a sample, 2nd time you owe"

That way they will either not want to pay and you get out of doin it again, or you have to do the trick but get paid.
Never tried it though, just thought of it so it may not work. Ya never know.

I usually say, "Gee, that's funny, I thought I did it pretty well the first time."

If they say let me see it again, i say, you have 2 eyes, you already saw it twice

can't you just say NO! ??????

sure, say no if you want....

No

Just tell them, "I do tricks...", "I don't do tricks AGAIN"

I can't do it again, I am a middle aged man, I do it once then roll over and go to sleep. Saying that will stop anyone.

LOL. funny stuff.

As anyone said here " Can you do it again?"
We know if we are doing magic tricks for the first times, it will be free.
And how about the second times?
" Can you do it again?" and I will say " How about 20$?" he he;)

That's make people thing for a while...
But I got 2 spectator that really like that trick. I really said "no" sorry.. Because the trick use a gimmick. he he! "The Invisible Deck!"

nice one

i'll say once is entertainment, twice is education

...and an education costs money.
