You sir, pineapple?
Photoshop or one of the other image editors for sale. Or just use paint and put more than five minutes into it. Also get a good joke before posting something. And make sure that all changes are relevent to the joke (or hard to see)
My advice: don't buy photoshop, you don't have the humor to use it properly, unless you need it for business, which you don't.
