(In addition to the straight-jacket thing, I opened it up a little).
It´s simple: open the image in a window, and show it a bit smaller than the window (you need room for your help lines and handles). Now, choose "Select - Select All".
Then choose "Edit - Transform - Perspective". Now, you´re rewarded with small, square "handles" at the corners of the image. Just pull either of the upper corners and see what happens.
A refinement: smack in the middle of the image is a small circle. This marks the centre that the image will be distorted around, and it is "draggable". Very useful, if an image is skewed both horizontally and vertically.
Experiment a little! Try the other transforms too! Note that it is easy to overdo this; perfectly straight verticals in a towering building looks unnatural.
Also, if you plan to do this, leave a little more space around the building when shooting it; it is needed so you can trim after the fact.

As I'm getting more and more comfortable with PS tools and things to make my pictures more, I've allowed myself to be led to the conclusion that pictures like this can be fixed to make verticals more vertical: http://www.geocities.com/tr_cunningham/durhamcath.html
My photography vocabulary is embarrassing. I am familiar with the keystone effect and was wondering if this picture exhibits the same thing, just in a different fashion. Or is there another term for it? Anywho, can this be fixed easily in PS? If so, which friggin' tool is used?
