The 10th grade biology teacher asked Jessica: "What part of the human body increases to 10 times it's normal size when excited?" Jessica responded: "I'm too embarrassed to answer!"
So the teacher asked Little Johnny who quickly said: "That's easy...the pupil of the eye." "That's correct, Johnny. Very good!"
And then turning back to Jessica, the teacher said: "I have three things to say to you, young lady... first, you didn't do your homework; second, you have a dirty mind; and third, you're in for a big disappointment!"
A ninety-year-old guy is walking by a lake when he hears, "Hi, there." He looks down, and it's a bullfrog. He picks it up, and the frog says, "If you kiss me, I'll turn into a beautiful princess." The old guy unzips his bag, puts in the frog, and starts to zip it back up. The frog says, "What are you doing?" The old guy says, "At my age, I'd rather have a talking frog."
