Look up Craig in Wiktionary, the free dictionary. Craig is an English-language masculine given name of an ultimately Celtic derivation. The name has two origins. In some cases it can originate from a nickname, derived from the Scottish Gaelic word creag, meaning rock, similar to Peter. In other cases, the given name originates from the Scottish surname Craig, which is also derived from the same Scottish Gaelic word. Cognate forms of creag include the Irish creig, Manx creg, and Welsh craig. The English word  crag  also shares an origin with these Celtic words.

So Craig is having fun with the ridiculousness of that.
