April 22, 1952: How undignified

Snoopy's expressions in panels 2 and 4 are cute. Of particular note here, this strip is rather busier than the standard four-panel Peanuts episode, with the "subplot" of Patty looking for the piece over to the side.

Note, on Comics.com's site, the day before is a reprint of this strip. I don't know what strip is supposed to be up for the 21st.

November 3, 1951: Gesundheit

Not really much of a joke here, but there hasn't been a lot of Snoopy in the last few weeks.

How about Shermy's expression, with his tongue out the side of his mouth? In the strip there have been two instances when this has been used: a character is eating or wants to eat, and when a character is focusing hard on something. I'm not really sure how either usage got started. Has anyone who's hungry ever stuck his tongue out like this? People hard at work might bite their tongues, but stick it out?
