50th birthday cake for my mom. What should i have written on it? - wakeboarding birthday card

This is the 50th Anniversary of my mother, and she is not enthusiastic. if we want the cake to be nice, do not laugh, she is 50 So we get a picture of my mother's wakeboarding on the cake. but I can not think of anything to write, to go with the photo of Wakeboarding? Please help? Thank you!
