7. Tennis Coach
Tennis Coach is kick-started when Franklin goes to Michael's home to see a man bailing out of an upstairs window, at which point we discover that Michael's wife Amanda has been cheating on him with her tennis coach. Cue lots of tennis-based innuendo, before Michael asks Franklin to help him chase the offender down, resulting in the two arriving at what they presume to be his mountain-side home, which they rig up to a steel cable and promptly rip from its shaky foundations. Moments later, the coach calls Michael up and tells him that the property wasn't his, and in fact it belonged to feared gangster Martin Madrazo, who then shows up at Michael's home and forces him to pay $2.5 million to rebuild the home, which sets in motion the very first heist mission. This mission may not last long at all, but it's pivotal in propelling the storyline forward, and is also absolutely hilarious.
