Ratshag is a Pirate

Read anything that Ratters writes in his Orcish alter-ego. Example here.

Now read how 8-Bit Theater portrays Bikke the pirate in Brian Clevinger's latest installment.

"I don't know what no 'medafrohicky' be, all I's knownin' is ye better turn this
ship about to shoot them broadside."

Tell me that you wouldn't mistake Orcish for pirate if you didn't know the characters involved.

Conclusion? Ratshag is a pirate.
