What are They Talking About????

Part I

Two guys walking out of the restroom:

First guy, "Man I didn't like how it felt in my hand. It was too large."

Second guy, "Yeah its like a hand cannon. Hard to hold."

Third guy gives them a strange look as he is going into the restroom.

Third guy says out loud. "What was that about?"

Fourth guy standing at the urinal laughing while he is looking down.

Was he laughing at what he was looking down at or the comments.

Translation: The two guys were talking about guns; different types of pistols.
Yes firearms.
Fourth guy was not laughing about what was in his hand, but the puzzlement of the third guy.

Part II

A guy walks into the office room were three other guys are at first thing in the morning.

He says to one of the guys, " Hey I saw a Viagra commercial this weekend
 that reminded my of you."

Room went dead silent.

I'm not even going to try and translate that. 

Careful what you say and be careful what you hear. It might not be what you think it is.
