Ha! That's funny! I have a useless talent of mocking Eric Cartman's voice and I used to have my best friend rolling when I would do his version of the ghetto song by Elvis!
Useless? Pfft. There are only 3 things in existence that are more useful than a solid Cartman impression.
1. A Leatherman tool
2. A 20lb bucket of Satin Ice
I can't tell you how many times a couple has thrown their cake samples back in my face during a tasting claiming that we had the worst cake they had ever tasted. Then as they were storming out, a mere "I hate you guys, I truly do" was all it took for them to turn about and hand me a wedding cake deposit check and tell me how much they look forward to working with me.
Other times I hit them with 20lbs of Satin Ice, stab them with my Leatherman tool and go home and watch Tivo.
I seriously need to start getting more sleep.
