Pie Eyed

I had two guys and one not so lovely lady in the cab this morning, one of the guys just happened to be gay.
 They had been out all night partying and were still totally steaming drunk. The over the top drunken lady all of a sudden comes out with the classic weird question “is your brother fat because you’re gay then”? 
There was a stunned silence for a minute or two and then the gay man said “no it’s because he eats too many pies” 
 Oh yes, she said," I eat pies too does that make me fat as well?” He just witheringly looked her up and down in scornful silence for a long moment and then they all started screaming and arguing at the top of their voices, luckily they had reached the destination and were getting out by then, boy was I glad to get rid of them.
