Has anyone ever sprung a surprise shower on anyone?

How do you keep it secret? I have a friend who is 7 months in to her first baby. She always finds out EVERYTHING. If I did not know better, I would think she had every friend she had and all their houses wired for spying!

I have been thinking how fun it would be to surprise her, she has been a little down lately and could really use some fun. But gosh darn it!

The only way I can think of to really pull the wool over her eyes would be to plan it at a bar! Hah!
