In all seriousness, find a foot operated tulip bulb planter. It pulls a cone shaped plug from the ground about 5" deep so a bulb can be dropped in and the dirt put back into the hole.
Put the dirt in a bucket you remove from the bare spot, go to a part of your yard where bermuda is growing nicely, and start removing plugs to be transplanted into the holes in the bare spot.
Fill in the holes in the existing bermuda lawn with the dirt from the bucket.
The advantage of plugging is that the roots are healthy, and 5" deep. Less watering, and a healthy plug is less likely to be effected by traffic on the yard or erosion. As it sends out runners, dig a small trench 1" deep with a hand trowell to bury the runner in. It will take root and send out its own runners. Keep a nitrogen fertilizer on it as that promotes runners and top growth.

I've got these.
Right now I'm waiting for the ground to dry out from the rain. Then I have to wait for the grinder to get the rest of the stump he missed. Then I can clean the shavings again. Then I can sprig Bermuda to my heart's content.
