Give her a fake number. You can find some good prank numbers online

Does she want to get into his briefs? Is her name Sue? Is the verdict that your brother has the preponderance of the height in your family? Is he going to court her? Let's not even get started with the hung jury...

She’s got some nerves. No tact. Not worth yours or your brothers time.

I predict that sooner or later your date will discover that she’s not in your tall and attractive brother’s league. Life can be a bitch - Some things about ourselves we can improve on if we set our minds to it like manners, a smile, how we dress, our education, and to a degree our physical condition. But there are some things we cannot change - Like our height, our overall build, and our intelligence. Concentrate on the things that you can improve yourself. There are men and women who are over-impressed by physical appearance. You cannot help those people if that’s all that’s important to them. But know that most of the pretty or handsome people are usually only interested in other pretty or handsome people. So chances are last night’s date won’t measure up to handsome brother’s requirements and she will have thrown away a potential relationship with you for no good reason. Give her brother’s contact info and tell brother she has the “hots” for him. He will likely either ignore her or use her - Either will likely hurt her as much as she hurt you and you won’t be at fault.
