let's have it

What do the phrases in bold mean?

Example:

"This explanation is probably tenuous at best."
"Let's have it."

Thanks!

1. The best you could say for this explanation is that it is tenuous. (It's not a convincing explanation).

2. I'm going to take a stab at this, even though a bit of context would be useful.
"Let's have it" = "Give it to me", or "Tell me the bad news".
