Marcus Porcius Cato the Elder (234BC-149BC) was a piece of work Gotta love him. Who else would toss a senator out of the Senate for embracing his wife in public while making jokes about his own "thundering" love life? Plutarch explains in his Life of Cato the Elder:
[After having been elected Censor in 184BC] Cato expelled another senator who was thought to have good prospects for the consulship, namely, [Manius] Manilius, because he embraced his wife in open day before the eyes of his daughter. For his own part, he [Cato] said, he never embraced his wife unless it thundered loudly; and it was a pleasantry of his to remark that he was a happy man when it thundered.
