Nice to know someone else thinks of 
this..there are some cels that have to go across 
from each other in the cel book! The top one may 
not be immediately obvious--but those cels are 
both the A1 cels from the scene in  No Need for 
Swimsuits, where Nagi and Ryoko face off...the 
middle two are pretty self-explanatory ;)--and I 
know the last two are from different seasons, but 
they just look like a demented tea party when you 
put them side by side!
