I always have a good chuckle when I hear people talking on the phone and their conversation consists of them repeating over and over again that they are on the bus, because most people realize it's not the ideal place to hold a conversation: it's loud and a tad inconsiderate the person sitting next to you.
One of my favourite moments of cellphone conversations, was a few years ago on the 11. There was a straight-laced WASPY business-man sitting on the side seat at the back, quietly talking on his cel, and then a few jovial aboriginal felows get on the bus, two sitting on the back seat and one beside him. He quietly puts away his phone, and immediately one of the dudes asks him if he can use it. He replies that "oh, maybe not." and the dude persists saying, "It's ok man, I just need to call a friend, I won't be long".
I think the businessman was a little scared of these guys, even though they seemed like they were harmless sweethearts, so he gives in and hands the dude his phone.
He calls his friend and the entire conversation is focused on how he is on the bus, which he repeats over and over again because the person he called will not believe that he could possibly be calling from the bus, "I'm on the bus! Yeah! I'm on the bus!". Finally after this goes on for about 5 minutes, he explains that they are on their way and he gives the businessman the phone back before a few more "Yeah! I'm ON THE BUS!"
A minute goes by and the cellphone begins to ring, the businessman reaches into his pocket and answers the phone, he asks the native fellow if his name is Gerald and says the phone is for him. Gerald gets back on the phone and continues the “I’m on the bus” conversation but the friend on the other end still won't believe him, "Yeah I just borrowed some white guys phone! - No, really! I'm on the bus!". He starts shouting, "I'm on the Bus, fuck!" over and over. Finally, he asks the businessman if he can convince his friend that he is indeed on the bus, to which he timidly agrees to, "Hello? Yes. Mmm-hmm, yes - he's on the bus."
