January 5, 1954: Snoopy and caramel

Read this strip at gocomics.com.

Should this go on the list of Snoopy powers?

Charlie Brown's mistake here is in assuming Snoopy is a dog.  He's more likely some kind of Shmoo-like creature.

Schroeder's reaction is made a lot funnier, I think, without a word balloon spelling out "HA HA" or something like that.

Chagrimace!

February 24, 1953: Snoopy the Opportunist

Further establishment of Snoopy's food-crazy personality.

Sometimes a crazy sight gag can stand on its own, and sometimes it needs a reaction frame to set it off. This one, I think, needs the reaction panel.

October 23, 1951: Finding only half a worm

Another Calvinesque strip, right down to Charlie Brown's angular smile in the last frame. I can picture Calvin doing this to Susie very clearly.

The outline of the tree in the third frame seems rather artsy for Peanuts. It's a nice effect though.
