Seven - one to actually change the bulb and six to complain that they liked the old one better.

Aye, Aye! Arrrr! & the Seven Seas!
Three. One to post it, and two to repost it.
X and V. There's a C between them.
Arr! It's driving me nuts!
A P. Because it's like an ARR, but it's missing a leg.
The ghost of BinBag the Whaler.
