Heh

Heh is often considered a go-to catchphrase for HH.

Impressions
HH very often looks to exude the image of a earthy cowboy. This mentality is redoubled by HHs Texas upbringing which very likely allows HH to imagine himself as a cowboy. As a result its often imagined that HH says heh in an attempt to sound really earthy and dry. Despite this HHs innumerable failures serve to destroy any appeal this would normally have.

Fading Away?
In more recent times HH has toned down the extent of how often he says "Heh" to the disappointment of his many Friends. Despite this HH continues to make new jokes to get made fun of for.
