My First Valentine's Day

So I'm sporting a new hairstyle these days, it's called a mohawk. I guess my parents were planning to give me one some day just for fun so I decided to beat them to the punch. I still can't figure out what a mullet is, though.
Yes, I've been working out, thanks for noticing. Check out my slimmed down waistline and nice, trim thighs. Oh, and look what I can do now:


Just like a dog, on command except I don't get a bone when I do it.

By the way, can anyone tell me what "jowls" are? Everyone says I have great ones and then smiles. I don't get it...
