Process of Elimination

There are two items of note in this picture. Can you identify what they are?

1) The first one is easy. Bradley is using his new booster seat. He had abandoned his baby seat several weeks ago. I guess his rationale is, if you don't sleep in a baby bed, you shouldn't sit in a baby chair.

2) Number two is actually number two. It is tough to tell from this picture, but Bradley has just finished using the potty for the first time. He seemed a little bewildered by the event, but then again, there were three people staring at him (and clapping). Personally, I usually don't like it when people watch me go to the bathroom. For the last few weeks, he would go into the bathroom, pull his pants down, and sit on the potty, but his diapers were still on. But yesterday, things were different. Here is the play by play - Brad signals dirty diaper, Auntie Lisa attempts to validate, the diaper is clean, but there an odor in the air, Lisa puts him on the potty, and a few seconds later, Mr. Hankey makes an appearance, applause ensues.
