I recall seeing one or two hands in the NVG High Stakes thread where someone bluffed river with blockers, got raised, and then decided they actually had to be good and called. Can't say I can recall having been in a spot like it myself.
edit:
I'll think it's FAR more common for one person to be bluffing with blockers, get rebluffed by air, and then call with say flush blocker. Imagine this:
Someone has A
Q
J
8
and pots the river on board 5
3
J
K
7
, gets raised, and decides to call because villain is repping something he can't have.
