That was a bit of a shit name but it surprises me that after so many years of pokémon the guy did not know he could not change the name of a traded pokémon.
One of my favourite quotes - ''...oh and youre not touching my DS if you touch my DS I will smash yours...''
Yellowducky for a Psyduck's nick name is lame. I usually call one PsyFuck

And I'll have a Zubat called Pubat.
I also saw so many Bidoof I have one called BiGoof amongst others. Oh that's it I have a Ratatta called Shatatta too.
