Hilarious: Woman pranked, sings for a free McDonald's meal

Some people will do just about anything for freebies.

Prankster Brad Holmes' latest prank made his missus Jenny Davies believe that she would get free McDonald's food for singing her order.

The missus, of course believing her very convincing Brad, puts on her best performance and sings for her cheeseburger order.

"May I please have a cheeseburger? And some fries?" she sang.

With Brad laughing next to her, Jenny can't help but get a bit annoyed.

"Why are laughing at me? You're putting me off, you keep laughing at me," Jenny can be heard saying in the video posted on YouTube.

She then continues to sing very confidently, "Do I get my free food?"

Nothing makes Brad laugh harder than seeing Jane fall for the prank.

See the hilarious reaction below. It will leave you in stitches.
