Channel surfing: 'Bachelorette' picks her man

The Bachelorette 4: It’s down to the last two guys, but none of this season’s North Texans is among them — the last one standing, Dallas’ Jeremy Anderson, was eliminated last week.

The Bachelorette: After the Final Rose follows, making for an all-Bachelorette night on ABC. 7 p.m., WFAA/Channel 8

Pollack’s Tootsie follows. 7 p.m., TCM
