Could I Still Get a Rise Out of You?

I heard from an old girlfriend today. We were just talking about general stuff, when, out of the blue, she asked, "So...can you still get it up?" I didn't expect that. "That just crossed your mind, did it?" I asked. "Yeah, apparently so" she replied. "Most guys your age have trouble in that area. So, can you?" 

 Here's basically what I said to her, in a nutshell: "Can I get it up? Ha-ha. Ha-ha-ha. Ha HAAA-ha-ha. HAAAAAAAAAA-HAAAAAA-HAAAAA. Ha-HA-HAAA-HAAAAAAAAAAAAAAA. HAAA-ha-ha."

 "HAAAAAA-HAAA-HAAA-HAAA-HA. HAAAAAAAAAAAA Ha-Ha-ha-ha-ha-ha-ha. Ha-HAAAAAAAAA HAAAAAAAA-HAAAAA-HAAA. Ha-ha-HAAAAAAAAAAAAAAAA-ha-ha-ha. Ha-ha. Ha. Whew. Yes."
