I thought that...
1. Women just randomly got pregnant and men had nothing to do with it and in order for someone to have a dad, their mom has to be married
2. In movies, they actually had magic and crap and there were no such thing as special effects
3. Men can breastfeed (I don't know)
4. Manatees are just cousins of mermaids
5. (This is when I was four btw) 5th graders are really just gifts from God.
