| (just fine, thank you...) Great! Say,   |

|                                         |
| (you just asked one...) Well, how about |
| one more?                               |
|                                         |
| (one more than the first one?) Yes.     |
|                                         |
| (you already asked that...) [at this    |
| point, Alphonso gets smart... ] May I   |
| ask two questions, sir?                 |
|                                         |

|                                         |
| (nope...) Then may I ask, sir, how I    |
| may ask you a question?                 |
|                                         |
| (yes, you may.) Sir, how may I ask you  |
| a question?                             |
|                                         |

|                                         |
| the number of questions you have asked, |

|                                         |
| next one) Sir, may I ask nine           |
| questions?                              |
