NOO fr ril

I asked Anders to get his jammies on, and he said "Wait! I have to make a really important sign before that."

"Really?  Ok, make the sign, then get your jammies on."  A few minutes later, he comes up to me with the sign.  It reads:

NOO

fr ril

"Ok," I say.  "Go get your jammies on."
Anders points to the sign. 
Me, incredulously: "what??"
Anders: "It says NO - for real."
Me: "So you're not going to get your jammies on?"
Anders: "The sign says no."
Me: "And that's the sign you that was so important that you had to make before you got your jammies on?"
Anders: "Yep."
