Marriage proposal – ‘ILY sign’ on a cake

One of my co-workers’ friend who is learning to become an interpreter recently proposed to his fiance with a cake that said “ILY” sign. I would have put up his picture but I don’t have his permission, tho.

That strikes me something. I haven’t never really thought about putting a ‘ILY sign’ on a cake. I wonder if that’s pretty common and wonder how many of you have done that.
