Badly drawn butts: Panel 4, if hips count. Elly looks like she's wearing jodphurs.
Woohoo! Jim lays the smackdown on Elly! Look at those bolds and underlines!
In panel 1, Elly demonstrates her maturity by glaring and pouting.
But what's the deal in panel 2? Her attention should already have been caught: when did she have time to exchange the cookie for the teacup so she could get caught in a fish-face instead of taking a sip?
And in panel 3, she still won't give it up. And meanwhile, Jim's dunking his cookie in her tea, which to me indicates that he's having some trouble chewing. See what he means? No, of course you don't; you can't see anything from way up there on that cross.
So in panel 4, she's off to find an enabler. Bye, El! Don't let the door hit ya...well, you'd have to move pretty fast to save that yard-wide butt. Anyway, toodles!
ETA: But one thing I wonder about. What is it with these people, that anyone younger than you is a "baby"? Yes, I know you'll theoretically always be your parent's baby, but right after he says that, Jim goes on to list all of Elly's adult responsibilities and accomplishments. That just really grates on me. The only baby in the strip is Robin.
