For too many of them, that would be just a typical Friday night. ;)
I remember watching CSPAN when Alabama Senator Howell Heflin had the floor.
Rumors were rampant that Senators Chuck Dodd and Ted Kennedy were on Kennedy's yacht off Florida doing an on-deck sandwich job.
Ol' Heflin spotted Senator Dodd arriving in the Chamber and commented in his drawl, "Why, I see the honorable Senator Dodd of Connecticut has arrived. I understand the good Senator has recently changed his position on 'OFF- SHORE DRILLING'!" (emphasis mine).
