A few questions spring to mind here before I answer this...
1.) would I have control over my invisibility??
If no then the first thing I would do is freak out
2.) could things I touch become invisible??
If so I would Touch my friends to freak them out
(Nothing like your own body disappearing, to freak someone out)
Also hiding things from people I know would be funny, allbeit irritating for the person in question. (You know thats why you can never find your Keys
)
Maybe a few pictures of people I hate in compromising positions
Oh and I would have to pay a few Attractive female celebrities a visit
