Richard Nixon's contained his pajamas, lost en route to Saudi Arabia from Anwar Sadat's funeral. Since a royal Saudi jet with solid gold bathroom fixtures (is there any other kind?) had been dispatched to Cairo to fetch him, he couldn't very well blame "the airline."

"Gosh," said the royal Saudi chief of protocol when he heard about the pj's, "I bought some new ones at Sulka's in London and never wore them. Be my guest."

Nixon accepted, and wore them throughout the Middle East as he dropped in on various potentates. Back home again, he called up the New York branch of Sulka's to order an identical pair (white with blue piping) for the Saudi official. "Above and beyond the call of duty," he wrote in a note that accompanied the pj's.

Rep. F. James Sensenbrenner Jr. (R-Wis.) packed more than pj's in his suitcase that disappeared at the Moscow airport last April. A longtime student of Soviet affairs, Sensenbrenner took six dozen birth control devices as a gift to a Russian friend who once had complained about the inferior quality of the Russian variety.

The bag turned up the next day with its contents intact but, Sensenbrenner suspects, not before Soviet authorities had raised a few eyebrows over what a U.S. congressman and his wife brought with them for a nine-day stay in Moscow.

In what Sensenbrenner says is a completely unrelated development, his wife, Cheryl, became pregnant during that same trip to Moscow and is expecting the couple's firstborn in a few weeks.

Sensenbrenner says his position on birth control is such that he doesn't have any problems with right-to-life groups. "But if what they say about when life begins is true," he wonders, "does it mean that citizenship begins then, too?"
