#3: A random WWE Live event

When Brock Lesnar chose not to follow through on his promise to cash-in on Seth Rollins during this week's RAW, fans weren't exactly thrilled.
Though the company tried to play it off as the wacky, unpredictable world of WWE entertainment, many fans saw it as another example of promising something to hook the fans, and not delivering.

If WWE did want to surprise fans (in a good way), then Lesnar cashing in at a Live event could certainly be the way to go.
After all, fans know how Lesnar's schedule works, meaning that no-one would dare expect the Beast to show up at a random house show unannounced.
If WWE really wants fans to believe that anything could happen, a Lesnar Live event appearance and World title change is definitely the right call.
