What are some of the stupidest things you’ve heard said at a tennis match?

Here are some of my favorite:

• Why are they counting by 15′s?  (30+15 does not equal 40)
• It hit the line it’s out.
• It’s out. It hit on the outside part of the line.
• I didn’t see where your serve landed can you serve again?
• You’re hitting the ball too hard it’s not fair.
• When is half-time?
• It’s easier if I let it bounce twice

Please share with me the stupidest things you’ve heard said and I will update the list as we go.
