English has a lot more of these crash blossoms--not just in headlines--than eg German or other more inflected languages.

It's sometimes charming, sometimes annoying. (But it makes for some cheap joke material that tends to make Poms think they are especially funny.)

I'm presuming the original headline was some variant of "Giant Banana Pulled Over in Montana: Driver Says Cops Have Stopped Him 100s Of Times" (originally submitted URL, since changed).

Mainly because the colon from the original was omitted, imo.
