"What's that?"; no rooting for Terrell Owens allowed

Isaac's very favorite book, given to him last Christmas by Great-Grandma and -Grandpa Peetz, is "Animals", which has more than a 100 different pictures of animals grouped together according to categories (i.e. "Farm Animals", "Colorful Animals", "Mini-Beasts"). There is almost no text to this book, so reading it consists of pointing to an animal, naming it, and making its sound. It is from this book that Isaac first caught on that "moo" = cow, "neigh" = horse, and "RRROAR!" = lion or other cat-like non-cat animal. Today we were reading it and he suddenly took an interest the animals I usually skip over, like Mr. Chameleon. At the chameleon, the elephant, the giraffe, Isaac would point and say, clear as day, "What's that?" He seemed to enjoy the elaborate detail I would then try to put into telling him what that exactly was, because he kept asking, with the starfish, the dolphin, the wolf...

This afternoon Dada and Isaac watched the Eagles game together while I napped. We are from Indianapolis and thus are rabid Colts fans, but Dada figured he should also pay a little attention to a "hometown" team, now that we are 45 minutes away from Philly. Being the Eagles, all the attention from the sportscasters and the writing on the screen focused on McNabb and his fabled receiver, Terrell Owens, known simply as "T.O." After being inundated with talk of this McNabb/T.O. combo, the report from Dada is that Isaac disappeared into his room, where he has a new chalkboard with magnetic letters on it. Completely alone, Isaac picks two letters from his set, only two, and brings them in to the living room to show Dada. Can you guess which two he might have picked? My genius monkey brought Dada a T and an O.
