As much as I love the whole Adam Sandler, Seth Rogen, Ben Stiller, Judd Aptaow schlemiel genre I always shudder a bit when finding out, again and again, that their co-star is a semi-serious perky blond. (For the most recent example, see the new movie “She’s Out of My League”, where the real-life half Jew Jay Baruchel pursues yet another, fair-haired and -eyed interest.) Why can’t the woman ever be funny — and not just spunky? Occasionally, a brunette? And, just once, Jewish?
