'Sheldon, why do I have to be Robin, if you hadn't noticed he's a boy and I'm a girl?'

'Robin is commonly a female costume when paired with Batman,' Sheldon explained. 'It is the logical choice if we are to win the costume contest at Comic Con.'

Penny whined staring at the website Sheldon was browsing, 'but couldn't I be someone cute like Cat Woman or Poison Ivy. They are beautiful with a hint of danger just like me,' Penny told him posing with her hands on her hips.'

Sheldon shook his head, 'Penny we have discussed this, you agreed to dress in my choice of costume for Comic Con if I gave you full power in choosing our Halloween costume. You have already procured a Barbie and Ken costume for this Halloween against my wishes. It is only fair you follow my wishes for this costume choice.'

'Fine, I will be stupid Robin as long as I get to choose the actual costume.'

Sheldon nods his head and points towards his screen; 'I would suggest this costume as it resembles Robin's costume for the early comics and will match mine with few alterations.'

Penny shook her head, 'no, it's ugly and clearly made for a man. I would look stupid in it plus you know Sheldon my blonde hair would completely ruin the look you're going for. Let me look,' she told him settling into his lap and stealing his mouse.

Sheldon wiggled in his chair at the extra weight of his girlfriend, 'Penny, this chair was built to only support the weight of one occupant at a time.'

Penny leaned over and stuck her tongue out at Sheldon, 'deal with it and that better not have been a clever way of telling me I'm fat,' she told him turning back to the screen and continuing to search the site he was on, 'ugly, ugly, never in a million years.'

'These are all perfectly comic actuate costumes,' Sheldon told her, 'there is nothing wrong with any of them.'

'Sheldon think about it this way, this will be your first time going to Comic Con with a hot girl willing to dress up with you and hang off your arm,' she told him wrapping her arms around his neck, 'if your going to bring a girl to Comic Con you need to worry less about how close her costume is to the real thing but instead on how beautiful she could look next to you. It's fun for me to look cute and its fun for you to be the guy all the other geeks are jealous of. Please let me pick the costume I want so we can make all the other nerds drool that I'm with you and not them.'

'Alright, I see your point. If I am going with a female I should let you show off your feminine wiles if you so wish,' Sheldon nodded staring at his girlfriend, 'I could always ask Leonard to wear the other costume for other cosplaying events. Which costume did you have in mind?'

Penny returned her fingers to the keyboard and typed in sexy robin costume into the search engine.
