Please help...sat on dookie?

I just sat down on the toilet without looking and I felt something different, got back up, and there was dookie on the toilet seat...and me! Ewww what do I do? How do I not get germs on my hands. I'm in a public bathroom and I am online on my phone and I have dookie all over me with nothing to clean it off with. Toilet paper ran out. EWWW please give suggestions, it stinks!
