What Do you Do when "Kidnapping" a 2 year Old?

I'm stuck I don't really know what to do with him other then the park and Ice cream and his mother will be giving him to me for the day, I get him as long as I want, I get to spoil him as much as I want, but I don't know what to do with him. He is a Fully Potty trained two and a half year old that like rainbows and bouncing, he calls moonwalks rainbows because of all the colors, I know he like to run and play and release energy he's two and a boy that's a given, but I am a poor college student and need idea's of what to do with a two year-old I get to "kidnap" for a day. I want it to be fun for both and I know he wont remember it when he's older, but if I'm still in his life it would be a fun story to tell. So any idea's at all are welcome, please give ideas, please.

For this sweet yet filthy face.


I also got a haircut and colored me hair it is quite a change for me.


Also my schools football team Kicks Ass my shirt says it all.

I know it's backwards, I took the picture into a mirror.
