I wouldn't worry too much playing against them either but I find them funny and sometimes very effective early on since they don't have any build time.
You can afford both an AG and T1 from the first second. Use your AG to rush for you opponents fuel and just sit in green cover/house and let him spend time and resources getting you out of there. A good choice can be an MG as second unit. If you manage to pull that start off you're in a great position and possibly even GG-material.
*Here you have two examples, one being like 3 minute long.
