Sometimes as part of the sentence. ("I am totally wearing my pink skirt today.")
Sometimes as an afterthought. ("I love this drawing.......totally.")
And then there's her favorite joke.
"Mom, can you look under there for me?"
"You said underwear!!" *hysterical laughter*
This whole bit is repeated over and over until I crack...usually four or five times. Once I decided I would outlast her. I would keep going until she got tired of it. Big mistake. It was an exercise in futility. After a full five minutes (that doesn't seem like very long, but seriously get a stopwatch and tell this joke over and over without a single pause for a full five minutes...it's an eternity) I finally cried uncle.
Then just this morning she was sitting on the couch and as I passed by she called out, "Mom! Hurry! Get on the couch! You're standing in the lava-poop!"
