It's a rehashed reprint (which we last saw on 1 July 2008) that has Elly freaking out about a non-event.
Panel 1: We start off with Mike, who just drank a can of Fizzo-Pop, contentedly belching thusly: "Burp-burp-burp-BRAAACK!!!"
Panel 2: This causes Elly's disembodied head to tell him that he is NOT to make those disgusting noises. (He should probably make these disgusting noises instead: CHOMP-CHEW-GLUT-SMACK-SLURP-SHLUUUUUUUCK-S
Panel 3: Having seized the offending can of soda, she tells him as he walks away he'd better understand that she doesn't want to hear him do that ever again.
Panel 4: He asks Lawrence how a guy is supposed to get good at something if he isn't allowed to practice.
Summary: He should instead be asking what kind of idiot freaks out because he belches while ignoring far worse behavior. Once again we see Elly go nuts because of piddly crap while not reacting to really bad things because she's stupid.
ETA: Here's yet another banner loaded with daffodils; I think we know what Lynn's favorite flowering plant is, don't we?
