Been reading Rinzler’s ESB book and one funny thing is that Harrison recognized and pointed out both continuity issues with the carbonite prop (wrong shirt and no shackles).
Not seeing what’s funny about that, but the Ugnaughts removed the binders and it was even shown in a close-up.
You’ve never heard the expression “funny thing”? Weird man, it’s a very common phrase and rarely refers to something that’s actually laugh out loud funny (usually just fun/interesting).
Harrison points both out and they Kersh decides to fix it by having Han be jacketless and show the cuffs removed. “Funny” because the shirt itself is still wrong and the continuity error about the shackles still prevails with many fans because of the ones on his arms (even though they likely wouldn’t prohibit the pose he makes).
Not seeing what’s “fun/interesting” about that, seems more of a mundane anecdote about how pretty much anyone would react.
