I remember a friend would troll me by obscuring a url which led to this website that hosted an image with a ridiculously large resolution for computer hardware of the time to render, resulting in a BSOD within 10 seconds. Got me every time!
this was still a problem until very recently. A few years ago I linked a 50k by 50k image in an IRC channel, 2 people experienced an X crash and one had a kernel panic.
