Jumping off 67P/Churyumov-Gerasimenko
If you can jump up 2.5cm on Earth, then you can jump off 67P/Churyumov-Gerasimenko and not come back (you would have to climb to the 'top' and jump in the direction of your spin). If you can jump a whole 10cm on Earth, you can leave 67P/Churyumov-Gerasimenko from any point and in any direction (you would have to bounce a few times if you pick a poor direction).
