“Noah” saounds like “know a,” prompting this pun that was viral on Twitter on September 8, 2010:
   
“Do you need to build an ark to save two of every creature? I Noah guy…”
 
“Need an ark? I noah guy”—the shortened version— is a jocular line that has been printed on many images. The “Noah” line is popular during heavy rains.
         
 
Wikipedia: Noah   
In the Abrahamic religions, Noah (/ˈnoʊ.ə/), or Noé or Noach (Hebrew: נֹחַ, נוֹחַ, Modern Noaẖ, Tiberian Nōăḥ; Syriac: ܢܘܚ‎ Nukh; Arabic: نُوح‎ Nūḥ; Ancient Greek: Νῶε), was the tenth and last of the pre-flood Patriarchs. The story of Noah’s Ark is told in the Torah in the Genesis flood narrative. The biblical account is followed by the story of the Curse of Canaan.

Ten Christian T-shirt puns to save the world

‘Need an Ark? I Noah guy!’
As relentlessly popular as it is inexplicably popular, this pun is available in countless designs – none of which make up for the linguistic atrocity it commits. Presumably it’s meant to convey the idea that Christians are actually supercool people and have a great sense of humour. It does not do this.
