In the garage, Stu challenges Tim to attempt to bench press 150 lbs. It is hard to tell exactly what weights are loaded on the bar because weights have been made to look different over time. Assuming best case, there are two 25s and two 5s on each side, totaling 120 lbs. Assuming worst case, there are two 35s and two 10s on each side, which is already more than 150. The weight of the bar itself must also be accounted for, which means the only way Stu could have been accurate is if Tim had a 30lb or less barbell. Standard barbells are almost always 45lbs. Occasionally a 35lb barbell can also be found. So this does not make sense.
