I saw a billboard on a bus today, and it literally made me laugh out loud. Emblazoned across the top were the words "The Evolution of Rock95 [rock 95 being our local rock station]"
Underneath these words was a series of stylized photographs depicting, in this order John Lennon, Mick Jagger, Gene Simmons of KISS, John Bon Jovi, and Chad Kroeger of Nickelback.
I'm pretty sure the intention involved a sort of generational 'tying-together' - although the use of Jagger AND Lennon is problematic considering they were contemporaries, so that kind of blows the intergenerational thing.
The humour to be found here lies in the billboard's subtext. They say a picture is worth a thousand words, but in this case it needs only about 10. With this picture, they might as well be saying
"The Evolution of Rock95 - We used to be cool, but now we kinda suck."
