In political controversy the impetuosity of his nature led him to be irascible and harsh towards his opponents and sometimes hasty in judgment. But towards those whom he liked he was equally effusive in expressions of regard, and was generous, high-spirited and placable. The fiery and impetuous temper of Otis is well illustrated by the following anecdote given by Tudor, who, however, does not vouch for its authenticity. Upon first taking his seat in the house, a friend sitting near, said: "Mr. Otis, you have great abilities, but are too warm, too impetuous; your opponents, though they cannot meet you in argument, will get the advantage by interrupting you, and putting you in a passion." "Well," said Otis, "if you see me growing warm, give me a hint, and I'll command myself." Later on when a question of some importance arose, Otis and this friend were on the Boston seat together. Otis said he was going to speak, and his companion again warned him against being irritated by interruptions from the opposition. He soon rose, and was speaking with great fluency and powerful logic, when Timothy Ruggles interrupted him; he grew warm in reply, and his friend pulled his coat slightly. Otis scowled as he turned round, but taking the hint moderated his tone. Soon afterwards, Mr. Choate, of Ipswich, broke in on him again. This aroused his temper, and his coat was pulled a second time; turning round quickly he said in an undertone to his monitor, "Let me alone; do you take me for a schoolboy?" and continuing his address with great impetuosity he overwhelmed his opponent with sarcasm and invective.
