Broadcaster Danny Baker has spoken about the tweet that got him sacked by the BBC in his first live show since the incident, saying: "When life deals you lemons, you chuck them at the people calling you racist."
He told the audience at the Theatre Royal in Nottingham his pacing up and down the stage was not a way of trying to "get away from potential Lee Harvey Oswalds".
Baker was sacked from BBC Radio 5 Live on Tuesday after tweeting a joke about the Duke and Duchess Of Sussex's son featuring a picture of a chimpanzee.
But he seemed defiant on stage, joking with the audience by saying "if anyone does want to rush the stage, I'm a Millwall fan with a snooker cue".
He told the audience: "I always pace the stage, I'm not trying to get away from potential Lee Harvey Oswalds.
"After 42 years in this racket ... I'm 62 nearly now and I thought, well, retire."
He then joked: "I didn't want to be forced to retire."
Wearing an orange shirt and a fez, the broadcaster went onto say his show would "ironically" be about the times his "career ... had hit a brick wall".
He said: "Topically, here we are again. That's the last time I'm going to mention it.
"That's the whole point of tonight. It's the most unlikely tower, and I'm stuck in it.
"It should never have happened."
Continuing to speak about the issue, the 61-year-old said: "I genuinely didn't know what the atmosphere would be like tonight.
"But equally, if anyone does want to rush the stage, I'm a Millwall fan with a snooker cue.
"You wouldn't believe how I was feeling 20 minutes ago but I'm so pleased so let's do this."
He added: "When life deals you lemons, you chuck them at people calling you a racist."
Opening the second half of the show, Baker said: "I've never been a sentimental sort. But I'm numb with gratitude tonight, I caught my wife in the break and you reduced her to a pile of tears."
At the end, he said: "I do want to say this and I'm not milking it but it's been one of the best nights of my career tonight. It really has."
He received a standing ovation as he made his way off stage.
