This is by no means an exhaustive list, and I'll have to see if I can figure out how to post videos or something to share the psycho cats and the snake-biting bunny (no, not snakebitten bunny, but the bunny who BITES a SNAKE!)... but in the meantime, enjoy the following items that have made me laugh like a loon today.
You'd have to have seen http://youtube.com/watch?v=JPONTneuaF4 to really get why this is so funny. But my husband and I now talk to one of his coworkers in this voice ALL the time. "Hi Marrrrrk!"
http://delilahpaints.blogspot.com/ This mom is hilarious. She's my age, and she's the kind mom I've thought I might be. And did I mention she's funny?
(Note, this list may grow... I don't know if being dayglo red and white like a candy cane makes me laugh more easily or not, but dude, I laugh at my own jokes DAYS later already... so God help John as he has to live with me laughing my face off every 20 minutes...)
