it has been claimed my bum is nimble

[VicNicSor]

Paul and Mac show up at a school ball committee meeting, and Mac's joking:
-- Can we just sit anywhere? We'll just sit anywhere. Not on any of you, clearly. On a... free seat. Though if any of you were offering, it has been claimed my bum is nimble.
The Fades, TV series

1. I think he should have kept it hypothetical till the end:
"If any of you were offering, it would have been claimed my bum is nimble."
Do you agree?

2. And, what does "nimble" here exactly mean?

Thanks.

No. He's saying that people have said in the past that his buttocks are quick and light in movement; agile: .

"Nimble Bum"? "Agile buttocks, quick in movement"?
Who are these men? ( Context?) I do hope to die laughing, but preferably not on WR.
