e.r. revisited

The man had to take the roommate to the E.R. again last night. This time, unlike last time (supposed food poisoning), was completely of the roommate's own doing. He got into a fight at the bar last night and ended up with a fractured clavicle and a big gash above his eye (all of which were described to me by the man, I do not care to fraternize with people who spend their time brawling). The event begs a few questions:

1. What was the roommate doing at a bar on a Monday night?
2. Who would fight with the roommate, who is approx. 6'5" and 300 lbs.?
3. What idiotic thing did the roommate do that caused the fight (probably hit on someone's girlfriend)?
4. Why didn't the roommate have his friends drive him to the E.R.? They drove him and his car back to the house at 12:45 AM.
5. Why did the roommate assume that the man would be willing to drive his sorry ass to the E.R. at nearly 1:00 in the morning?

I do not care enough to ask these questions, but I think it quite humorous that the roommate (who bounced his rent check again) had enough money to go to the bars seven out of the last ten nights. Quite humorous in the way that you laugh because something is so preposterous that you don't know what other action would be warranted.
