Reference to Home Improvement: Mike references Wilson. When Vanessa and Eve are shooting arrows, Mike tells Vanessa to aim low to avoid hitting the weird guy that gives him advice (while hiding the lower part of his face).
The title of this episode, "Heavy Meddle", was also the name of a Home Improvement episode season 2 episode 5.
Tim Allen even pays homage to the character of Wilson from Home Improvement when Mike Baxter mentions his weird neighbor always giving him advice.
