My wife and I had just finished tucking our five young ones into bed one
evening when we heard sobbing coming from three- year-old Billy's room.
Rushing to his side, we found him crying hysterically. He had accidentally
swallowed a penny and was sure he was going to die. No amount of talking
could change his mind.

Desperate to calm him, my wife palmed a penny that she happened to have
in her pocket and pretended to pull it from Billy's ear. Billy was
delighted. In a flash, he snatched it from my wife's hand, swallowed it
and demanded cheerfully, "Do it again, mum!"

The average cost of rehabilitating a seal after the Exxon Valdez oil 
spill in Alaska was $80,000. At a special ceremony, two of the most 
expensively saved animals were being released back into the wild amid 
cheers and applause from onlookers. A minute later, in full view, a 
killer whale ate them both.

In a biology class, the prof was discussing the high glucose levels found 
in semen. A young female (freshman) raised her hand and asked "If I 
understand, you're saying there is a lot of glucose, as in sugar, in male 
semen?"
"That's correct", responded the prof, going on to add statistical info. 
Raising her hand again, the girl asked, "Then why doesn't it taste sweet?" 
After a stunned silence, the whole class burst out laughing, the poor 
girl’s face turned bright red, and as she realized exactly what she had 
inadvertently said (or rather implied), she picked up her books
without a word and walked out of class...and never returned. However, as 
she was going out the door, the Profs reply was classic... Totally 
straight-faced he answered her question, he stated
"It doesn't taste sweet, because the taste-buds for sweetness are on the 
tip of your tongue".
