Only, this couldn't be just lunch. It would need to be a full day at an amusement park or something. They say that laughter is the best medicine. I'm pretty sure that after a day with these two Yahoos, nothing would ail a body. (Remember the rule is that it is two people who would be more fun together- I am not suggesting these two are a "couple")
And if Owen wants to invite his brother... you know... so there's even numbers to go on roller coasters- then I won't argue.
