TONIGHT'S MUST-SEE

"How I Met Your Mother," 7:30 p.m., CBS. On the right weeks, this first-season show has been just shy of hilarious. Here's a rerun of one such episode. Ted goes to a matchmaker (Camryn Manheim). She's immensely unhelpful.

"How Art Made the World: The Day Pictures Were Born," 10 p.m., PBS. In the late 19th century, ancient cave paintings were discovered. Similar work was eventually found around the world, perplexing scholars. Fortunately some relatively recent paintings are from a nomadic tribe, the San, which still clings to its old ways. Visiting the San in Namibia, this interesting hour learns more about man's first artistic urges.

"Kyle XY," 8 p.m., ABC Family. Last week's likable debut saw the family adjusting to the fact that Kyle — a teen-looking chap with no discernible roots — was staying with them. Still, they were creeped out by the fact that he never sleeps. Tonight, he tries to.
