The Preposition "On"

The other day Jeff and I were talking about all of the things that we have experienced with the birth of Jack. I started naming off a list of things that had particularly happened to me, and Jeff turned to me and said, "You're prepositionally challenged!" He's right. See for yourself.

In four weeks I have been:
Cried on
Sneezed on
Puked on
Pooped on
Peed on
Sucked on
Burped on
Boogered on
Slept on
Screamed on
Tooted on
Breathed on
Gazed on
Splashed on
Frowned on
Smiled on
Loved on

The list goes on
And isn't he worth every one?
