Take 5: All the president's children

The new NBC comedy "1600 Penn" (which previews Monday night) concerns the domestic life of a fictional first family, with emphasis on its off-kilter 20-something son played by Josh Gad ("The Book of Mormon"). And somehow this reminds us that several real-life presidential kids have gone on to careers, of sort, in show biz. Take these five:

1. STEVEN FORD -- The youngest son of Gerald and Betty Ford played private investigator Andy Richards on the soap "The Young and the Restless."

2. RON REAGAN -- Ronald and Nancy Reagan's son has had a varied entertainment-biz career, including hosting a late-night TV talk show and a syndicated radio talk show.

3. PATTI DAVIS -- The Reagans' daughter had guest-starring roles in such late 1970s-early '80s series as "The Love Boat," "CHiPs," "Nero Wolfe" and "Fantasy Island," and a role on the syndicated soap opera "Rituals."

4. CHELSEA CLINTON -- Bill and Hillary Clinton's daughter is a correspondent for NBC News.

5. JENNA BUSH HAGER -- George W. and Laura's fraternal-twin daughter is a correspondent for NBC's "Today" show.
