DH used to 'get' our sons - every year. One year, it was the plastic frog in the toilet - another year - plactic wrap over the toilet. They still laugh that they fell for it year after year.

This a.m. - I reminded him that it was April Fools Day (as he prepared to go off to the golf course with his buddies.) He just winked at me and said - "of course I remember." Which kept me on my toes for the rest of the day - wondering.... Haven't found anything yet - but the day's not over either.
