Answer:
He said he had no frog.
Explanation:
In the short story "The Notorious Jumping Frog of Calaveras County", written by Mark Twain, Jim Smiley boasts with his intelligent frog. His frog's name is Dani'l Webster, and according to Smiley, it can jump more than any other frog in the world. The stranger challenges Smiley to a contest, but he says he's got no frog, so Smiley goes to search for a frog for the stranger.
While Smiley is searching for the frog, the stranger feeds Smiley's frog with lead, so that it becomes heavy and can't jump. That's how the stranger won the contest, and by the time Smiley realised what really happened, he was long gone.
