As we know it is possible to jump over the flagpole in Super Mario Bros, are there any secrets or easter eggs beyond them? Growing up I heard rumors that there was a secret pipe if you ran far enough, however I'm skeptical now that I'm older since it appears that it's more of an unintended exploit than a "secret".
This question applies to the original or any remakes of the original.
It appears to be at the end of stage 3-1. (source)
I've unfortunately never been able to perform this trick. The potential of 99 lives does you no good if you die every time you go for it.
From the screenshot shown on that page, it appears that the coin blocks have been relabeled with "25". I hope, at least, that this was the only "partially rearranged" issue in the 25th anniversary of a classic.

The ability to jump over the flagpole is a glitch. As per the Super Mario Wiki:
There is no secret pipe and while the regular game will just have the timer run out on the player, when using a cheat to disable the timer the player can run far enough to cause the game to glitch.
