Maybe he just has it tucked-away ;)
OR like:
Some creatures don`t like to get 
their ..well..err.., hmm.. their tails wet ^-^ 
hahaha..I`m sorry I couldn`t resist.
No wonder Vegita is angry all of the 
time...sorry, it`s hard to stop once I get 
started..Speaking of which, where is "ol`sparky" 
anyway?...didn`t make the cut!! opps..there I go 
again..looking for that mysterious Saiyan organ 
cel..be kinda "difficult" (see i didn`t use the 
word `hard`) to find or indeed ask for where that 
missing link..er I mean, cel is to be found. I 
guess that you could have one made up..but then 
that request would be kinda weird too..like how 
big it should be and all that, right?? How 
embarassing, a penis correction cel request! 
Oops! sorry...it`s a great Pan cel though, beyond 
all of the hoopla..really nice exposure ^-^.
