For D&D, the best is Order of the Stick.
I'd say it was Rusty & Co, but that's just an online comic thus far; Order's the one collected into books.
For Catholic, I might mention Rick Cook's Limbo System, even though the priest's thread is only one of the plot lines.
"Rat Queens" looks like it might be as good, if it keeps going the way it is. But it's only a few issues old.
