To dress up or not?

How many of you out there still dress up for Halloween? How many of you dress up your pets?

I think the last time I dressed up was when I was 10 or 11. I found out  that I have to dress up this year for a party, so its time to start looking for costumes. I  don’t like to dress up so I always look for ways out of it. I think it's the mask that always has me dreading Halloween. 

I am a big Adam Sandler fan and so I decided to dress up as Happy Gilmore. All I need is a Bruins Jersey, sweatpants and Black boots. Living in Massachusetts I already own two of these, so I only have to go out and buy blue sweatpants.  All I have left to do is to bring some of my golf clubs with me. Are there any other easy costumes that wont cost much money and make it feel like your not really dressed up? I may need those ideas for next year. 

As for the pets I have a 6 month old German Shorthaired Pointer. My wife wants to dress him up for Halloween. I am not sold on this but most likely lose the battle and let her dress him up. The only problem is that large costumes for dogs are sold online and not in stores. 

Since I am set up with my costume already please let me know what costume I should get for Wrigley. I would love to know any web sites that have good deals on dog costumes as well. All help and recommendations would be great! These are my top 5 so far.
