The best thing about this strip is the lead panels, the two that some newspapers would strip out. That hilariously cold way Charlie Brown greets Lucy, who immediately shows why he's responding that way. It's difficult to mistake "fussbudget" for a compliment this time.
Linus' display of skill is typical for him -- almost everything he tries he turns out to be great at. Imagine Charles Schulz sitting hunched over his desk, thinking of all the ways be can write out the word "bumpety" and "bump."
Imagine him doing that, and imagine him thinking to himself afterwards, "How did I manage to land this wonderful job?"
