Revealing mistake: When Fletcher is beating himself up he goes into a stall and squishes his head with a toilet seat. You can see that the white part underneath is made out of foam because it keeps squashing down.

More questions & answers from Liar Liar





Answer: As you said, he was testing to see if the wish was broken--by going up to an attractive woman and talking to her. While we don't hear what happens, he apparently said something a little too "forward" to her (probably more forward than he would have done otherwise, hence the "not as well as I had hoped"), and got slapped, so he knew that he was still under the wish's effects.

But I want to know what he said to the woman.
It's deliberately made unclear what he specifically said, because him getting slapped in the face is the gag that shows the audience that he's still under the spell. If we heard what he said, then we would know right away the new wish wouldn't have worked. It's ultimately up to the viewer's imagination to decide what he told the woman.
