Re the Zeberpupin cartoon, loved the earlier comment about Wally programming in "Z" as in "zzzzzzzzz" :o)
Good cartoon and (as usual with Dilbert) is actually an issue for businesses:

Clearly, Zeberpupin is highly proprietary! As for Wally programming in 'Z', it then becomes obvious that when you see him face down on his desk going 'Z-Z-Z-Z-Z-Z', he's actually generating source code!
