Like you suggested, these shouldn't be taken too 
seriously...

- A seller says a cel includes the 
sketch/background but they don't know if it's 
stuck because they never open the bag. 
(translation: the cel is stuck)

- People who constantely complain about 
"resellers" even though they are guilty of it 
themselves. (of course they have a good reason!)

- Sellers who ship cels rolled in a tube.

- The hissy-fits that erupt in this forum every 
now and then... the people who claim to be 
supportive of other collectors, yet wont share 
the link to *insert angelic choir here* Pocket 
*end choir* 

- That pesky dint between cel layers that the 
seller failed to mention.

- The post office cart that ran over my package 
last Christmas.

Wow.. the list could go on and on~! :)
