Where the quote actually comes from:
“I am just one hundred and one, five months and a day.”
“I can’t believe that!” said Alice.
“Can’t you?” The Queen said in a pitying tone. “Try again: draw in a long breath and shut your eyes.”
Alice laughed, “There’s no use in believing impossible things.”
“I daresay you haven’t had much practice.” Said the Queen. “When I was your age, I always did it for half an hour a day. Why sometimes I’ve believed as many as six impossible things before breakfast.”
